EPSS · scored 2026-10-27

OpenClaw versions 2026.1.16-2 prior to 2026.2.14 contain a path traversal vulnerability in archive extraction during installation commands that allows arbitrary file writes outside the intended directory. Attackers can craft malicious archives that, when extracted via skills install, hooks install, plugins install, or signal install commands, write files to arbitrary locations enabling persistence or code execution.

    Ein Angreifer kann diese Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen oder andere, nicht näher bezeichnete Angriffe durchzuführen.

    ## 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.
