CVE-2026-92628 GitLab CVE debrief

Who should care

GitLab CE/EE administrators and users who rely on the MCP search tool should assess exposure and prioritize patching or implementing compensating controls. This includes reviewing the official advisory or CVE record to validate affected scope, severity, and vendor guidance. Additionally, defenders should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and review compensating controls for exposed

Why it matters

Defenders should prioritize verifying and applying patches for GitLab CE/EE versions 18.6 to 19.4.1, assessing exposure and implementing compensating controls if necessary, as the MCP search tool's shared state handling could have caused search results to be returned under an incorrect user context under a race condition.

• Verify and apply patches for GitLab CE/EE versions 18.6 to 19.4.1 to prevent potential incorrect user context issues
• Assess exposure and implement compensating controls if necessary to mitigate potential risks
• Monitor for potential exploitation attempts to detect potential security incidents
