EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 77% 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 before 2026.5.7 contains a privilege escalation vulnerability in the Matrix allowFrom feature that allows authenticated accounts to match policy entries through mutable display name metadata. Attackers with the ability to change display names can receive agent access intended for another Matrix identity, potentially gaining unauthorized permissions depending on operator configuration.
