OpenClaw has a local file disclosure via sendMediaFeishu in Feishu extension

High severity GitHub Reviewed Published Feb 15, 2026 in openclaw/openclaw • Updated Feb 20, 2026

Package

npm openclaw (npm)

Affected versions

< 2026.2.14

Patched versions

2026.2.14

Description

Summary

The Feishu extension previously allowed sendMediaFeishu to treat attacker-controlled mediaUrl values as local filesystem paths and read them directly.

Affected versions

  • < 2026.2.14

Patched versions

  • >= 2026.2.14

Impact

If an attacker can influence tool calls (directly or via prompt injection), they may be able to exfiltrate local files by supplying paths such as /etc/passwd as mediaUrl.

Remediation

Upgrade to OpenClaw 2026.2.14 or newer.

Notes

The fix removes direct local file reads from this path and routes media loading through hardened helpers that enforce local-root restrictions.

Fix commit 5b4121d60 confirmed on main and in v2026.2.14. Upgrade to openclaw >= 2026.2.14.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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.
