Aliases CVE-2026-28457
Summary OpenClaw's sandbox skill mirroring path traversal vulnerability could write outside the sandbox workspace ## 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.
