Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
OpenClaw versions before 2026.2.14 allow local attackers to write arbitrary files outside the sandbox directory through path traversal sequences in crafted skill package names when sandbox skill mirroring is enabled. An attacker can exploit this by providing a malicious skill package with traversal patterns like ../ or absolute paths in the frontmatter name parameter, potentially compromising system integrity. A patch is available to remediate this vulnerability.
Technical ContextAI
Classified as CWE-22 (Path Traversal). Affects Openclaw. 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.
RemediationAI
A vendor patch is available — apply it immediately. Validate and sanitize file path inputs. Use allowlists.
