EPSS · scored 2026-10-27

OpenClaw versions prior to 2026.2.14 contain a path traversal vulnerability in sandbox skill mirroring (must be enabled) that uses the skill frontmatter name parameter unsanitized when copying skills into the sandbox workspace. Attackers who provide a crafted skill package with traversal sequences like ../ or absolute paths in the name field can write files outside the sandbox workspace root directory.

  • WID-SEC-W-2026-0424OpenClaw: Mehrere SchwachstellenDeutsch2026-02-15csaf · cert_bundDE

    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.

  • GHSA-xw4p-pw82-hqr7OpenClaw's sandbox skill mirroring path traversal vulnerability could write outside the sandbox workspace2026-03-02ghsa · osvUS

    ## Overview In affected versions, OpenClaw’s sandbox skill mirroring used the skill’s frontmatter `name` as part of the destination path when copying skills into the sandbox workspace. A crafted skill name containing traversal segments (for example `../`) or an absolute path could cause the copy to write outside `<sandbox_workspace>/skills/`. ## Impact - Files may be written outside the sandbox workspace root (within the permissions of the user running OpenClaw). ## Attack Requirements - Attacker can provide a skill package (controls `SKILL.md` frontmatter). - Victim runs with sandbox enabled and skill mirroring into the sandbox workspace. ## Affected Packages / Versions - `openclaw` (npm): `< 2026.2.14` ## Fixed In - `openclaw` (npm): `>= 2026.2.14` ## Fix Commit(s) - 3eb6a31b6fcf8268456988bfa8e3637d373438c2 OpenClaw thanks @1seal for reporting.
