CVE-2026-22171Network attack vector

Arbitrary file write via Feishu media keys

Published Mar 18, 2026 · Updated Mar 18, 2026

Path traversal in OpenClaw before 2026.2.19 allows remote attackers to write files outside its temporary directory via Feishu media keys. The Feishu media download functions in extensions/feishu/src/media.ts interpolate imageKey and fileKey into paths passed to SDK writeFile operations without neutralizing traversal segments. Exploitation requires control of media-key values returned to the client, and writes remain limited to paths permitted for the OpenClaw process.
