description

OpenCSG CSGHub through v2.6.0-ce is affected by an authorization bypass in its unauthenticated file-resolution functionality. A remote unauthenticated attacker may access files from private repositories when they can reach that route.

mitigation

Restrict or disable unauthenticated access to the file-resolution route and limit the portal service API key to only necessary permissions. Monitor for a vendor-fixed CSGHub release and upgrade promptly when one is available.
