Official description

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.
