EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 65% 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).

A fix is available — apply it.

OpenClaw before 2026.5.12 contains a shell option parsing vulnerability that allows combined POSIX shell flags to bypass exec revalidation checks. Attackers can exploit this by using combined shell options to execute inline shell content without intended allowlist validation, potentially enabling unauthorized command execution when the affected feature is enabled.
