CVE-2026-53976

Bohdan Triapitsyn OpenChamberVulnerabilityCVSS 9.3

OpenChamber 1.11.7 contains a path traversal vulnerability in the file-serving endpoints /api/fs/read, /api/fs/stat, and /api/fs/raw that allows unauthenticated remote attackers to read arbitrary files by supplying the allowOutsideWorkspace=true query parameter alongside an absolute path, bypassing the workspace boundary check in resolveReadPathFromContext. Attackers can exploit the vacuous isPathWithinRoot guard to read sensitive files such as the JWT signing secret, SSH private keys, API credentials, and environment variables, enabling full authentication bypass by forging session cookies on password-protected deployments.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
