Any client can therefore enumerate agents and send arbitrary messages, which may be interpreted as commands or data by the agents and their tool sets. The lack of authentication permits an attacker to potentially trigger unintended behavior, including remote code execution or information disclosure, by manipulating message payloads. This weakness corresponds to missing authentication (CWE-306).", "risk_and_exploitability": "The vulnerability receives a CVSS score of 9.1, indicating critical severity. No EPSS score is available, and the issue is not listed in the CISA KEV catalog, yet the absence of authentication suggests high exploitability from an external network client. Attackers only need to connect to the /ws endpoint, enumerate agents via /info, and send crafted messages. The straightforward access model implies that exploitation can occur without privileged credentials or complex prerequisites."}}}}, "created": "2026-04-06T21:21:50.007858+00:00", "updated": "2026-04-06T22:21:27.260153+00:00", "vendors": ["mervinpraison", "mervinpraison$PRODUCT$praisonai"]}
