MEDIUMPre-NVD 5.15.1—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 94% 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.

A logic vulnerability (fail-open condition) has been identified within the Metasploit Framework's JSON-RPC web service interface. When an exception occurs during the database health check (db.check) and the environment variable MSF_WS_JSON_RPC_API_TOKEN is not explicitly set, the application resets the internal state flag msf.auth_initialized to false. The ApiToken Warden authentication strategy misinterprets this false value as an indicator that authentication is not initialized or required, thereby granting unauthenticated local access to the JSON-RPC request dispatcher.
