CVE-2026-22171: Openclaw Path Traversal Vulnerability
MODERATECVE-2026-22171 is a MODERATE path traversal vulnerability (CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) affecting Openclaw libraries in the npm ecosystem. The issue involves openclaw vulnerable to path traversal in feishu media temp-file naming allows writes outside os.tmpdir(). Remediation is available by upgrading affected packages to version 2026.2.19.
CVE-2026-22171 at a Glance
How to Fix CVE-2026-22171
To remediate this vulnerability, upgrade all affected Openclaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install openclaw@2026.2.19Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls openclawHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-22171, inspect your project dependencies using npm:
npm ls openclawAnalyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.19), your application is affected.
Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product 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 product 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. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"summary" : "OpenClaw vulnerable to path traversal in Feishu media temp-file naming allows writes outside os.tmpdir()",
"details" : "## Summary\n\nOpenClaw’s Feishu media download flow used untrusted Feishu media keys (`imageKey` / `fileKey`) when building temporary file paths in `extensions/feishu/src/media.ts`.\nBecause those keys were interpolated directly into temp-file paths, traversal segments could escape the temp directory and redirect writes outside `os.tmpdir()`.\n\n## Impact\n\nThis is an arbitrary file write issue (within the OpenClaw process file permissions).\nIf 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.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Latest published npm version at triage: `2026.2.17`\n- Affected versions: `<= 2026.2.17`\n- Fixed version: `2026.2.19`\n\n## Fix Commit(s)\n\n- `c821099157a9767d4df208c6b12f214946507871`\n- `cdb00fe2428000e7a08f9b7848784a0049176705`\n- `ec232a9e2dff60f0e3d7e827a7c868db5254473f`\n\n## Remediation\n\nThe 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.\n\nOpenClaw thanks @allsmog for reporting.",
