CVE-2026-53976: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Bohdan Triapitsyn OpenChamber
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.
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 supply the allowOutsideWorkspace=true query parameter 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 on deployments protected by passwords.
Potential Impact
An unauthenticated remote attacker can read arbitrary files on the server running OpenChamber 1.11.7, including sensitive secrets such as JWT signing keys, SSH private keys, API credentials, and environment variables. This exposure allows attackers to forge session cookies and fully bypass authentication mechanisms, potentially leading to complete compromise of the affected 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 OpenChamber services to untrusted networks.
