Summary
OpenClaw vulnerable to path traversal (Zip Slip) in archive extraction during explicit installation commands
Details

Summary

A path traversal (Zip Slip) issue in archive extraction during explicit installation commands could allow a crafted archive to write files outside the intended extraction directory.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: >=2026.1.16-2 <2026.2.14
  • Fixed version: 2026.2.14

Affected Commands / Flows

This only affects users who run installation commands against an untrusted archive (local file or download URL), for example:

  • openclaw skills install (download+extract installers)
  • openclaw hooks install (archive installs)
  • openclaw plugins install (archive installs)
  • openclaw signal install (signal-cli asset extraction)

It is not triggered by receiving messages or normal gateway operation.

Impact

Arbitrary file write as the current user. In the worst case this can be used for persistence or code execution if an attacker can convince a user to install a crafted archive.

Fix

  • Fix commit: 3aa94afcfd12104c683c9cad81faf434d0dadf87
  • Released in: 2026.2.14

Credits

OpenClaw thanks @markmusson for reporting.
