Bohdan Triapitsyn · Openchamber · CVE-2026-53976
**Name of the Vulnerable Software and Affected Versions**
OpenChamber version 1.11.7
**Description**
An issue exists 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 providing an absolute path and setting the `allowOutsideWorkspace` query parameter to `true`, attackers can bypass the workspace boundary check within the `resolveReadPathFromContext()` function. This occurs because the `isPathWithinRoot` guard is vacuous, potentially exposing sensitive data such as JWT signing secrets, SSH private keys, API credentials, and environment variables, which could lead to a full authentication bypass via forged session cookies on password-protected deployments.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Avoid using the `allowOutsideWorkspace` parameter in the '/api/fs/read', '/api/fs/stat', and '/api/fs/raw' endpoints.
