OpenClaw versions prior to 2026.2.19 contain a path traversal vulnerability in the Feishu media download flow. The vulnerability exists in extensions/feishu/src/media.ts where untrusted media keys are directly interpolated into temporary file paths. An attacker who can control Feishu media key values can use directory traversal segments to escape the temporary directory and write arbitrary files within the OpenClaw process permissions. This allows unauthorized file system access and potential system compromise.
