• CVE-2026-9950LOW 3.1

  A same-origin policy bypass vulnerability exists in Google Chrome on iOS versions prior to 148.0.7778.216. The flaw stems from insufficient validation of untrusted input that allows an attacker who has already compromised Chrome's renderer process to craft a malicious HTML page that circumvents browser security boundaries. This means an attacker could potentially access data or perform actions from a different website origin than the one a user is visiting, but only if the renderer process has already been compromised through another attack vector.

• CVE-2026-44367LOW 2.7

  Klaw, a Kafka topic management and governance platform, contains a vulnerability in how it handles usernames during registration and login. The system doesn't consistently apply case sensitivity rules—treating 'Admin' and 'admin' as different or the same depending on the operation—which allows authenticated users with administrative privileges to deliberately lock out accounts or trigger denial of service conditions. This is a low-severity issue requiring administrative access to exploit, but it can impact operational availability if administrators use it maliciously or if the inconsistency is exploited in targeted attacks. The flaw was fixed in version 2.10.4.

• CVE-2026-45076LOW 2.7

  Synapse, an open-source Matrix homeserver implementation used for federated messaging, contains a flaw in how it handles room history in cross-server deployments. Malicious homeservers can craft specially formed room events that cause Synapse instances to withhold historical messages from clients requesting older conversation data. Users may see incomplete chat histories or missing messages when paginating through room archives. This is a low-severity issue because it requires a compromised or malicious federated peer and affects data availability rather than confidentiality or integrity.
