EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 62% 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 before 2026.3.22 performs cryptographic and dispatch operations on inbound Nostr direct messages before enforcing sender and pairing policy validation. Attackers can trigger unauthorized pre-authentication computation by sending crafted DM messages, enabling denial of service through resource exhaustion.
