EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 61% 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 2026.2.2 contain an exec approvals (must be enabled) allowlist bypass vulnerability that allows attackers to execute arbitrary commands by injecting command substitution syntax. Attackers can bypass the allowlist protection by embedding unescaped $() or backticks inside double-quoted strings to execute unauthorized commands.
