Description

OpenClaw vulnerable to path traversal in Feishu media temp-file naming allows writes outside os.tmpdir()

Summary

OpenClaw’s Feishu media download flow used untrusted Feishu media keys (imageKey / fileKey) when building temporary file paths in extensions/feishu/src/media.ts.

Because those keys were interpolated directly into temp-file paths, traversal segments could escape the temp directory and redirect writes outside os.tmpdir().

Impact

This is an arbitrary file write issue (within the OpenClaw process file permissions).

If an attacker can control Feishu media key values returned to the client (for example via compromised upstream response path), they can influence where downloaded bytes are written.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version at triage: 2026.2.17
  • Affected versions: <= 2026.2.17
  • Fixed version: 2026.2.19

Fix Commit(s)

  • c821099157a9767d4df208c6b12f214946507871
  • cdb00fe2428000e7a08f9b7848784a0049176705
  • ec232a9e2dff60f0e3d7e827a7c868db5254473f

Remediation

The fix removes key-derived temp-file naming and keeps downloads in safe temp locations. Additional hardening isolates SDK writeFile calls in per-download temp directories (mkdtemp) with deterministic cleanup, enforces Feishu key trust-boundary validation, and adds a repository guard test against dynamic path.join(os.tmpdir(), \...${...}\) patterns in runtime code.

OpenClaw thanks @allsmog for reporting.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must actively cooperate. Rated impact: confidentiality high, integrity none, availability none.

  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Attack requirements: None — no deployment-specific condition has to hold.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: Active — the victim has to cooperate with the attack.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.

Weakness class

CVE-2026-22171 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
