CVE-2026-53976: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Bohdan Triapitsyn OpenChamber
OpenChamber 1.11.7 has a critical path traversal vulnerability in its file-serving API endpoints that allows unauthenticated remote attackers to read arbitrary files by bypassing workspace boundary checks. This can expose sensitive files such as JWT signing secrets, SSH private keys, API credentials, and environment variables, enabling full authentication bypass on password-protected deployments.
AI Analysis
Technical Summary
OpenChamber version 1.11.7 contains a path traversal vulnerability in the /api/fs/read, /api/fs/stat, and /api/fs/raw endpoints. Attackers can exploit the allowOutsideWorkspace=true query parameter combined with an absolute path to bypass the workspace boundary check implemented in resolveReadPathFromContext. The ineffective isPathWithinRoot guard allows reading of arbitrary files, including sensitive secrets and credentials. This vulnerability enables unauthenticated attackers to forge session cookies and bypass authentication mechanisms on deployments protected by passwords.
Potential Impact
An unauthenticated remote attacker can read arbitrary files on the server, including sensitive secrets such as JWT signing keys, SSH private keys, API credentials, and environment variables. This exposure allows the attacker to forge session cookies and fully bypass authentication controls, potentially compromising the entire system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the vulnerable endpoints and monitor for suspicious activity. Avoid exposing the affected API endpoints publicly if possible.
