CVE-2026-28453: OpenClaw < 2026.2.14 - Zip Slip Path Traversal in TAR Archive Extraction

Severity: critical (CVSS 9.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.4% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-03-05 · updated 2026-06-17
Weakness: CWE-22

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.

Affected products

OpenClaw: before 2026.2.14 — fixed in 2026.2.14

How to fix

Upgrade to a fixed version: OpenClaw 2026.2.14. Check the vendor advisory for mitigations.
