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.

EchelonGraph scoreLOW confidence
This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
