• CVE-2026-56211HIGH 7.1

  A vulnerability in libaom, the open-source AV1 video codec library, allows an attacker to execute arbitrary code on systems that process untrusted video files with scalable video coding (SVC) features enabled. An attacker crafts malicious video frames that bypass safety checks in the encoder, allowing them to corrupt memory structures that control how the encoder operates. In services that spawn separate processes to handle video encoding, this memory corruption can be leveraged to discover the process layout in memory and ultimately redirect execution to attacker-controlled code. Exploitation requires that the target application uses libaom with SVC encoding active and processes video frames from an untrusted source.

• CVE-2026-56275HIGH 7.1

  Flowise versions before 3.1.0 contain a server-side request forgery (SSRF) vulnerability in the Execute Flow node. An authenticated attacker can manipulate the base URL field to bypass security controls and force the application to make HTTP requests to internal network addresses, cloud metadata endpoints, and other sensitive systems that should not be directly accessible. This allows reconnaissance and potential lateral movement within your infrastructure.

• CVE-2026-56280HIGH 7.1

  Cap-go versions before 12.128.2 contain a privilege escalation flaw in their build log streaming feature. An attacker with a read-only API key—which should only permit viewing logs—can actually cancel active native builds by connecting to the log stream and then disconnecting. This happens because the server uses its own privileged credentials to clean up when clients disconnect, rather than checking whether the client itself has permission to cancel builds. The vulnerability allows repeated disruption of build pipelines and CI/CD workflows without requiring elevated API credentials.

• CVE-2026-56314HIGH 7.1

  Capgo, a mobile app deployment and update platform, contains a flaw that allows attackers with valid credentials to push outdated or intentionally removed app versions to end-user devices. The vulnerability stems from incomplete data filtering when retrieving available app versions during update checks. An authenticated attacker can exploit this by deploying bundles that were previously deleted, potentially exposing users to known bugs, security issues, or malicious code embedded in those older versions. This is a moderate-to-significant risk because it requires authentication but can affect the integrity of deployed software at scale.

• CVE-2026-6858HIGH 7.1

  The Transbank Webpay WordPress plugin before version 1.14.0 contains a stored cross-site scripting (XSS) vulnerability in its logging functionality. An unauthenticated attacker can inject malicious code into plugin logs, which is then executed in the browser of any administrator who views those logs. This allows attackers to steal administrative credentials, modify site content, or perform actions as if they were a logged-in administrator.

• CVE-2026-8035HIGH 7.1

  CVE-2026-8035 is a denial-of-service vulnerability in National Instruments' PAL kernel driver that allows authenticated local users to crash the system. The flaw stems from inadequate input validation that fails to check for NULL pointers before dereferencing them in memory. An attacker with local system access can exploit this by supplying malformed input to the driver, causing an immediate kernel panic. The vulnerability affects NI-PAL version 26.3.0 and all earlier releases across both Windows and Linux platforms.

• CVE-2026-8036HIGH 7.1

  NI-PAL, National Instruments' process abstraction layer, contains an input validation flaw that allows authenticated local users to read and modify arbitrary memory regions on affected systems. An attacker with local access could exploit this to escalate their privileges. The vulnerability affects NI-PAL version 26.3.0 and earlier on both Windows and Linux platforms.

• CVE-2026-8089HIGH 7.1

  The weMail WordPress plugin contains a reflected cross-site scripting (XSS) vulnerability that allows attackers to trick authenticated users—including administrators—into clicking malicious links. When a victim clicks a crafted URL, malicious JavaScript executes in their browser with their privileges, potentially allowing attackers to perform actions on their behalf, steal session tokens, or modify site content. The vulnerability exists because user input is not properly sanitized before being inserted into HTML attributes in AJAX responses, and the vulnerable endpoint lacks nonce protection to validate legitimate requests.

• CVE-2026-8172HIGH 7.1

  The Simple Basic Contact Form WordPress plugin fails to properly sanitize user input when displaying form validation errors, allowing attackers to inject malicious JavaScript code into the page. An attacker can craft a malicious link or form that, when visited by a site user, executes arbitrary JavaScript in that user's browser within the context of the vulnerable website. This type of attack, known as Reflected Cross-Site Scripting (XSS), can be used to steal session cookies, perform actions on behalf of the user, or redirect them to phishing sites.

• CVE-2026-8874HIGH 7.1

  Securly Chrome Extension version 3.0.7 downloads security configuration files—specifically crisis alert keywords and filtering rules—over plain HTTP instead of the encrypted HTTPS protocol. While the same extension correctly uses HTTPS for other sensitive data (IWF and CIPA filtering data), this inconsistency leaves downloaded crisis alert configurations vulnerable to interception and modification by network-positioned attackers. An attacker on the same network could intercept these files and inject malicious keywords or rules, potentially disrupting the extension's security functionality or causing it to behave unexpectedly.

• CVE-2026-9570HIGH 7.1

  The Taskbuilder WordPress plugin before version 5.0.8 contains a reflected cross-site scripting (XSS) vulnerability in its frontend shortcode functionality. An attacker can craft a malicious URL containing JavaScript code that, when visited by a logged-in user, executes in the context of that user's browser session. The vulnerability stems from inadequate sanitization of a URL parameter before it is output directly into inline JavaScript code on the page. This allows an attacker to hijack user sessions, steal sensitive data, or perform actions on behalf of the victim within WordPress.

• CVE-2026-9808HIGH 7.1

  Mautic 7's API has a flaw where user permission restrictions aren't being honored properly. Specifically, permissions designed to let users only see or edit their own resources (called 'owner-scope' restrictions) are being bypassed. An attacker with low-level API access can exploit this to view or modify other users' data, even though they shouldn't have that permission.

• CVE-2024-38487HIGH 7.0

  CVE-2024-38487 is a container escape vulnerability affecting api-gateway containers that run with root privileges. An attacker with local access to a system running a vulnerable api-gateway container could break out of the container and gain access to the underlying host system, potentially allowing them to modify, delete, or disable critical services and data. The vulnerability requires local access and some effort to exploit, but the consequences—full host compromise—are severe.

• CVE-2026-0083HIGH 7.0

  A race condition in Android's NFC (Near Field Communication) event handling code allows a local attacker with basic system access to escalate their privileges to access sensitive data or modify system files. The vulnerability requires precise timing exploitation but no special permissions or user interaction to trigger, making it a significant local security concern.

• CVE-2026-0125HIGH 7.0

  CVE-2026-0125 is a race condition vulnerability in Android's VPU (Video Processing Unit) driver that allows a local attacker to escalate their privileges. An attacker with a low-privilege local account can trigger a use-after-free condition in the vpu_ioctl.c file by timing requests carefully, potentially gaining higher-level access to the device without needing special permissions or user interaction. This is a serious flaw because it requires only local access and basic user privileges to exploit.

• CVE-2026-34335HIGH 7.0

  A use-after-free memory vulnerability exists in Windows Ancillary Function Driver for WinSock (AFD.sys), affecting Windows 10 and Windows 11 across multiple versions, as well as Windows Server 2012 through 2025. An authenticated local attacker can exploit this flaw to escalate their privileges to SYSTEM level. The vulnerability requires local access and specific conditions to trigger, but once exploited, grants complete control over the affected system.

• CVE-2026-41108HIGH 7.0

  A memory safety flaw in Windows DNS could allow someone with local system access to break out of normal restrictions and gain full control of the computer. The vulnerability exists because DNS processes input in a way that can overflow a memory buffer, and an attacker positioned locally—such as a low-privilege user or service—could exploit this to run code with elevated permissions. This is not a remote vulnerability, but it poses a significant risk in multi-user or shared-system environments.

• CVE-2026-42462HIGH 7.0

  Fedify, a TypeScript library for building federated applications using ActivityPub, contains a vulnerability that allows attackers to manipulate cryptographically signed activities without invalidating the signatures. By exploiting JSON-LD (JSON Linked Data) restructuring techniques, an attacker who receives a validly signed activity from a third party can alter its meaning and content while the Linked Data Signature remains valid. This breaks the integrity guarantee that signatures are supposed to provide, enabling attackers to forge or modify federated messages in a way that appears authentic.

• CVE-2026-42836HIGH 7.0

  A race condition in Windows' Function Discovery Service (fdwsd.dll) allows a user already logged into a machine to escalate their privileges to administrator level. The vulnerability exists because the service does not properly synchronize access to shared resources when multiple processes run concurrently, creating a narrow window where an attacker can manipulate the process. An authorized user would need local access and specific timing to exploit this, but successful exploitation grants full system-level permissions.

• CVE-2026-42911HIGH 7.0

  A use-after-free memory vulnerability exists in Windows' Ancillary Function Driver for WinSock (AFD.sys). An attacker who already has local access to a machine can exploit this flaw to gain elevated privileges, potentially running code with system-level permissions. The vulnerability requires specific conditions to trigger—it is not trivially exploitable—but once successful grants significant control over the affected system.

• CVE-2026-42912HIGH 7.0

  A race condition in Windows Telephony Service allows an attacker who already has local user access to exploit improper synchronization of shared resources and gain system-level privileges. The vulnerability requires the attacker to perform specific timing-dependent actions during concurrent operations—making it moderately difficult to exploit in practice, but reliably escalatable once triggered. No user interaction is required beyond the attacker's ability to run code as a local user.

• CVE-2026-42984HIGH 7.0

  A use-after-free memory vulnerability exists in the Windows Kernel that allows an authorized local user to escalate their privileges to a higher level of access. An attacker with standard user permissions could exploit this flaw to gain system-level control on an affected machine. The vulnerability requires local access and specific conditions to trigger, but successful exploitation would grant complete compromise of the target system.

• CVE-2026-44495HIGH 7.0

  Axios, a widely-used HTTP client library for JavaScript applications, contains prototype-pollution gadgets that can be exploited if another vulnerability in the same process has already poisoned JavaScript's Object.prototype. The issue affects versions 0.19.0 through 0.31.0 in the 0.x branch and version 1.15.1 in the 1.x branch. By itself, Axios does not cause the initial prototype pollution; instead, it becomes a secondary target once an attacker has already compromised Object.prototype through a separate vulnerability. When this occurs, Axios may incorrectly interpret inherited properties as legitimate request configuration, leading to potential code execution or data exposure. The vulnerability is addressed in Axios 0.31.1 and 1.15.2.

• CVE-2026-44604HIGH 7.0

  A flaw in RPM's archive extraction tool allows an attacker to run arbitrary commands on a system by crafting a malicious archive with shell metacharacters embedded in its folder name. When a user extracts such an archive using the rpmuncompress utility, the unsanitized folder name is passed directly into a shell command, enabling code execution with the privileges of the extracting user. The vulnerability affects ZIP, 7z, and GEM archive formats.

• CVE-2026-44818HIGH 7.0

  A race condition vulnerability in Microsoft Office Excel could allow an attacker to execute code on a user's computer. The flaw arises from improper synchronization when multiple processes access shared resources simultaneously. An attacker would need to trick a user into opening a malicious Excel file, but once triggered, the vulnerability can grant full control over the affected system. The vulnerability affects multiple versions of Excel and Office across 365 subscriptions, on-premises deployments, and older perpetual licenses.

• CVE-2026-45596HIGH 7.0

  A use-after-free vulnerability in the Windows Ancillary Function Driver for WinSock (AFD) allows an authenticated attacker to elevate their privileges on a local system. The vulnerability requires the attacker to already have user-level access and involves a race condition during memory management. Successfully exploiting it grants the attacker full system-level control.

• CVE-2026-45597HIGH 7.0

  A race condition vulnerability in Windows UI Automation Manager allows an authorized local user to escalate privileges on affected systems. The flaw arises from improper synchronization when multiple processes access shared resources simultaneously. An attacker with existing local access can exploit timing windows to gain system-level privileges. This is not a remote vulnerability and requires prior authentication or local access, which narrows but does not eliminate the risk in shared computing environments.

• CVE-2026-45598HIGH 7.0

  A race condition in Windows' Ancillary Function Driver for WinSock (AFD.sys) allows an attacker who already has local access to a system to escalate their privileges to a higher level. The vulnerability stems from improper synchronization when the driver handles shared resources, meaning that under specific timing conditions, an attacker can exploit the flaw to gain elevated permissions. This is not a remote attack—the attacker must already have a foothold on the machine, such as a low-privileged user account or compromised application context.

• CVE-2026-45601HIGH 7.0

  A race condition in the Windows Ancillary Function Driver for WinSock allows someone already logged into a Windows system to escalate their privileges to a higher level of access. The vulnerability arises from improper synchronization of shared resources, meaning two processes can interfere with each other when accessing the same data simultaneously. An attacker with local user privileges can exploit this timing-dependent flaw to gain elevated system rights, though doing so requires specific conditions and is not trivial to reproduce reliably.

• CVE-2026-45603HIGH 7.0

  A race condition vulnerability exists in Windows' Ancillary Function Driver for WinSock (AFD) that allows an authorized local user to escalate privileges to a higher level on the system. The flaw arises from improper synchronization when multiple processes access a shared resource simultaneously, creating a narrow window of opportunity for an attacker to manipulate the driver's behavior. An authenticated user with basic local access can exploit this to gain elevated privileges, potentially achieving full system compromise. This is not a remote vulnerability and requires the attacker already has some level of access to the target machine.

• CVE-2026-45640HIGH 7.0

  A use-after-free vulnerability in the Windows Bluetooth Port Driver permits a user with local system access to escalate their privileges to a higher level. The flaw exists because the driver fails to properly manage memory when Bluetooth port operations conclude, leaving a freed memory region accessible for malicious manipulation. An attacker must already have some level of local authentication and user rights to exploit this issue, but successful exploitation grants full system control.

• CVE-2026-45653HIGH 7.0

  A heap-based buffer overflow vulnerability in the Windows Kernel allows a user with local system access to overflow a memory buffer, enabling them to execute code with elevated privileges. The attack requires an authenticated user account and moderate technical effort to exploit, but if successful grants attacker control over the affected system. This is a local privilege escalation issue, not a remote attack vector.

• CVE-2026-46154HIGH 7.0

  A race condition exists in the Linux kernel's scheduler extension (sched_ext) cgroup interface that can lead to use-after-free memory access. When system administrators adjust cgroup scheduling parameters like weight, idle status, or bandwidth, the kernel reads a pointer to the scheduler without proper synchronization. If another process simultaneously disables and re-enables a different scheduler, the cached pointer becomes stale and points to freed memory. When the original operation tries to use this pointer, it dereferences already-freed kernel memory, potentially allowing local privilege escalation.

• CVE-2026-46164HIGH 7.0

  A memory management bug in the Linux kernel's Btrfs filesystem can cause the same memory region to be freed twice when a sysfs initialization step fails. This double-free condition can lead to memory corruption and potentially allow an attacker with local access to crash the system or execute code with elevated privileges. The issue occurs in error handling code that wasn't properly coordinated between two layers of the filesystem's initialization logic.

• CVE-2026-46299HIGH 7.0

  CVE-2026-46299 is a lock-handling bug in the Linux kernel's HFS+ filesystem driver that can allow a local attacker with moderate privileges to crash the system or potentially escalate privileges. The vulnerability occurs during filesystem mount when the code acquires a lock but fails to release it properly if certain filename validation steps fail. This causes the system to detect a memory leak while a critical lock is still held, triggering a kernel warning and potential system instability.

• CVE-2026-46309HIGH 7.0

  CVE-2026-46309 is a memory access control flaw in the Linux kernel's GPU driver (xe) that can leak sensitive data. When a privileged process uses a low-coherency GPU memory mode on CPU-cached buffers, the GPU can bypass CPU caches and read stale data directly from RAM—including sensitive information from previously freed memory of other processes. The fix validates GPU memory configuration requests to prevent this dangerous combination.

• CVE-2026-47293HIGH 7.0

  A use-after-free vulnerability exists in Microsoft Office's Click-To-Run installation and update mechanism. An attacker with valid credentials on a local machine can exploit a memory management flaw to gain elevated (administrator) privileges. This is not a remote vulnerability—it requires an authorized user account and local access—but the privilege escalation risk makes it a meaningful threat in environments where credential compromise or insider activity is a concern.

• CVE-2026-47648HIGH 7.0

  CVE-2026-47648 is a privilege escalation vulnerability in Windows Storage that affects multiple versions of Windows 10, Windows 11, and Windows Server. An authorized local user can exploit an untrusted search path flaw to gain elevated privileges on a compromised system. The vulnerability requires local access and user interaction is not needed, but exploitation depends on specific system conditions. With a CVSS score of 7.0 (HIGH), this poses a meaningful risk to environments where local account compromise is plausible.

• CVE-2026-54229HIGH 7.0

  A timing vulnerability exists in the abrt-dbus D-Bus service that allows a local attacker with limited privileges to take control of crash dump files while the system is processing them. The vulnerability stems from a race condition where the ChownProblemDir method changes file ownership even though privileged event handlers are actively writing to the same directory. An attacker exploiting this can redirect, modify, or delete crash dumps before they're fully processed, potentially compromising system integrity and enabling local privilege escalation.

• CVE-2026-54230HIGH 7.0

  A vulnerability in libreport's ABRT (Automatic Bug Reporting Tool) event handler scripts allows a local attacker with limited privileges to overwrite arbitrary files on a system. The flaw occurs because event scripts use file output redirection without protective measures that would prevent following symbolic links. An attacker can replace a target file with a symlink pointing to a sensitive system file, then trigger an ABRT event. Since the event scripts run as root, they unwittingly follow the symlink and write data to the attacker's chosen location, potentially corrupting critical system files or planting malicious content.

• CVE-2026-54321HIGH 7.0

  Daytona, a platform for running AI-generated code securely, had a caching bug that allowed certain sandboxes to remain publicly accessible even after their owners switched them to private. If an organization marked a preview sandbox as private, the system's cache did not update immediately, creating a window where unauthenticated users could still access the sandbox and potentially view or interact with code and data that should have been restricted. This gap has been closed in version 0.184.0.

• CVE-2026-6090HIGH 7.0

  CVE-2026-6090 is a HIGH severity authentication bypass vulnerability in Lenovo Smart Connect for Windows that allows an authenticated local user to gain elevated system privileges and run arbitrary code. An attacker already logged into the system could exploit this to escalate their access and take full control of the machine. The vulnerability requires local access and some specific conditions to trigger, making it a meaningful risk for shared systems or environments where user accounts are provisioned broadly.
