HIGHNVD 8.88.8—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 70% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenClaw versions prior to 2026.2.21 fail to filter dangerous process-control environment variables from config env.vars, allowing startup-time code execution. Attackers can inject variables like NODE_OPTIONS or LD_* through configuration to execute arbitrary code in the OpenClaw gateway service runtime context.
