CVE-2026-28453 PUBLISHED

OpenClaw < 2026.2.14 - Zip Slip Path Traversal in TAR Archive Extraction

Assigner: VulnCheck
Reserved: 27.02.2026 Published: 05.03.2026 Updated: 09.03.2026

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.
