Path Traversal in OpenClaw Sandbox Skill Mirroring Allows File Write

Publication date: 2026-03-05

Last updated on: 2026-03-09

Assigner: VulnCheck

Description
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.

Executive Summary

This vulnerability exists in OpenClaw versions prior to 2026.2.14 and involves a path traversal issue in the sandbox skill mirroring feature. When this feature is enabled, it uses the skill frontmatter name parameter without proper sanitization while copying skills into the sandbox workspace. Attackers can exploit this by providing a specially crafted skill package with traversal sequences like "../" or absolute paths in the name field, allowing them to write files outside the intended sandbox workspace root directory.

Impact Analysis

The vulnerability allows attackers to write files outside the sandbox workspace, potentially leading to unauthorized file creation or modification on the system where OpenClaw is running. This can compromise the integrity of the system by overwriting or adding files in sensitive locations, which may lead to further exploitation or disruption of normal operations.
