Last modified

CVE-2026-28453 is a high-severity vulnerability rated 8.3/10 on the CVSS scale. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
