EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.5 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 95% of all CVEs by exploit prediction. 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).

OpenClaw versions 2026.1.16-2 prior to 2026.2.14 contain a path traversal vulnerability in archive extraction during installation commands that allows arbitrary file writes outside the intended directory. Attackers can craft malicious archives that, when extracted via skills install, hooks install, plugins install, or signal install commands, write files to arbitrary locations enabling persistence or code execution.
