CVE-2026-53976
CriticalCVSS 9.1Summary
Path traversal vulnerability in OpenChamber 1.11.7 in file-serving endpoints /api/fs/read, /api/fs/stat, and /api/fs/raw, allowing unauthenticated remote attackers to read arbitrary files by supplying allowOutsideWorkspace=true and an absolute path, bypassing workspace boundary check.
Risk Assessment
An attacker can read sensitive files such as JWT signing secret, SSH private keys, API credentials, and environment variables, enabling full authentication bypass by forging session cookies.
Recommendation
Update OpenChamber to a patched version or apply a workaround such as restricting access to these endpoints.
Original NVD description (English source)
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.
