Each password change forces the database to rehash the password string, which can drastically increase query latency. The weakness is a resource depletion flaw identified as CWE\u2011400, allowing an attacker to exhaust server resources and degrade performance for legitimate users.", "risk_and_exploitability": "The flaw requires an attacker to be authenticated with an account that has permission to alter role passwords, so initial compromise or legitimate credentials are prerequisites. EPSS data is unavailable and the vulnerability is not listed in the CISA KEV catalog, but the lack of a public exploit combined with the high impact of performance degradation suggests a moderate to high risk, especially for production environments where Cassandra is critical. The likely attack vector is through CQL traffic to the database, which, if exploitable, can be performed remotely over the network. Timely patching is therefore essential to reduce exploitation likelihood and protect service availability."}}}}, "created": "2026-04-08T19:36:42.635378+00:00", "updated": "2026-04-08T19:47:46.029303+00:00", "vendors": ["apache", "apache$PRODUCT$cassandra"]}
