CVE-2026-69110 Microck CVE debrief

Who should care

System administrators and security teams responsible for OpenCode Studio deployments should be aware of this vulnerability and take immediate action to verify and mitigate it. This is particularly important for environments where OpenCode Studio is exposed to the internet or untrusted networks.

Why it matters

CVE-2026-69110 is a critical vulnerability in OpenCode Studio that allows unauthenticated remote attackers to read arbitrary files and delete videos. System administrators and security teams should verify and mitigate this vulnerability, especially in exposed environments.

• Potential unauthorized access to sensitive information such as intermediate audio, video artifacts, and subtitles
• Potential deletion of videos by ID through the unauthenticated DELETE endpoint
• Need for verification of OpenCode Studio version and exposure
• Priority on upgrading to version 2.4.4 or later

Technical summary

The vulnerability exists in OpenCode Studio before version 2.4.4, allowing unauthenticated remote attackers to read arbitrary files within the temp and static/music directories by directly accessing the GET /api/tmp/:tmpFile and GET /api/music/:fileName endpoints. Attackers can also delete any video by ID through the unauthenticated DELETE /api/short-video/:videoId endpoint. This vulnerability is particularly concerning as it enables attackers to access sensitive information such as intermediate audio, video artifacts, and subtitles belonging to other users' jobs. System administrators and security teams should verify and mitigate this vulnerability, especially in exposed environments.

Defensive priority

High priority should be given to verifying and mitigating this vulnerability, especially for systems or deployments using OpenCode Studio versions prior to 2.4.4.

Recommended defensive actions

• Verify OpenCode Studio version and upgrade to 2.4.4 or later if necessary
• Restrict access to the /api/tmp/:tmpFile and /api/music/:fileName endpoints
• Implement authentication and authorization for the DELETE /api/short-video/:videoId endpoint
• Monitor for suspicious activity on the affected endpoints
• Perform a thorough review of system logs to identify potential exploitation attempts
• Conduct an asset inventory to identify all instances of OpenCode Studio
• Review and update incident response plans to include procedures for handling potential exploitation of this vulnerability

Evidence notes

The CVE record and NVD entry provide details about the vulnerability, including its critical CVSS score of 9.3 and the affected versions of OpenCode Studio. However, the exact scope of affected systems and the extent of potential exploitation remain unclear.
