OpenClaw's sandbox skill mirroring path traversal vulnerability could write outside the sandbox workspace
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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)
