CVE-2026-10073: DreamMaker Arbitrary File Read via Relative Path Traversal

Technical summary

CVE-2026-10073 is an Arbitrary File Read vulnerability in DreamMaker stemming from improper handling of relative file paths (CWE-23). The vulnerability allows unauthenticated, network-based attackers to traverse directory structures and download files outside their intended access scope. The CVSS 3.1 score of 7.5 (HIGH) reflects a network attack vector with low complexity, no privilege requirement, and no user interaction needed. Impact is confined to confidentiality; integrity and availability are not affected.

Business impact

Exploitation of this vulnerability could expose sensitive system files, configuration data, credentials, or intellectual property stored on affected systems. Organizations using DreamMaker face data exfiltration risk without the need for an attacker to authenticate or compromise user accounts first. The lack of privilege requirements and ease of exploitation increase the likelihood of opportunistic attacks targeting exposed instances.

Affected systems

DreamMaker as developed by Interinfo is affected. Verify your deployment version against vendor advisories to confirm impact scope. No specific affected product versions are listed in the current advisory; contact Interinfo or consult their security documentation for version-specific guidance.

Exploitability

This vulnerability is highly exploitable. It requires no authentication, no special user interaction, and presents low attack complexity, meaning a standard HTTP request or simple script can trigger the path traversal. The network-accessible attack vector means any system with network exposure to DreamMaker is at immediate risk. The flaw is straightforward to weaponize once the path traversal mechanism is understood.

Remediation

Patch DreamMaker to a version that properly validates and sanitizes file path inputs, removing the relative path traversal vulnerability. Coordinate patching with your DreamMaker deployment documentation and Interinfo's official advisory. Until patches are available, restrict network access to DreamMaker instances using firewall rules and network segmentation to trusted networks only.

Patch guidance

Monitor Interinfo's official security advisories and update channels for available patches. Apply patches promptly following your change management process. Verify patch effectiveness by retesting path traversal attempts in a non-production environment. Document patch versions applied and maintain an inventory of DreamMaker instances to ensure comprehensive coverage.

Detection guidance

Monitor DreamMaker access logs for patterns suggesting path traversal attempts, such as requests containing '../' sequences or unusual file paths in request parameters. Network intrusion detection systems can flag HTTP requests with traversal patterns. Log file access events and flag reads of sensitive system files from DreamMaker processes. Baseline normal access patterns and alert on deviations.

Why prioritize this

Although CVE-2026-10073 is not on the CISA KEV list, its HIGH CVSS score, combined with unauthenticated network exploitability and low attack complexity, warrants prompt attention. Any organization running Internet-exposed DreamMaker instances should prioritize patching before external threat actors identify and exploit exposed systems.

Risk score, explained

The CVSS 3.1 score of 7.5 (HIGH) reflects the combination of network accessibility, complete confidentiality impact, no required authentication or user interaction, and low attack complexity. The absence of integrity or availability impact prevents a CRITICAL score. Organizations should treat this as a high-priority security issue despite not yet appearing on the KEV catalog.
