Severity CVSS v4.0:

HIGH

Type:

CWE-22 Path Traversal

Publication date:

05/03/2026

Last modified:

Description

OpenClaw versions prior to 2026.2.14 fail to validate TAR archive entry paths during extraction, allowing path traversal sequences to write files outside the intended directory. Attackers can craft malicious archives with traversal sequences like ../../ to write files outside extraction boundaries, potentially enabling configuration tampering and code execution.
