10.04.2026, 17:17

OpenClaw before 2026.3.24 contains a path traversal vulnerability in sandbox enforcement allowing sandboxed agents to read arbitrary files from other agents' workspaces via unnormalized mediaUrl or fileUrl parameter keys. Attackers can exploit incomplete parameter validation in normalizeSandboxMediaParams and missing mediaLocalRoots context to access sensitive files including API keys and configuration data outside designated sandbox roots.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
