An attacker who can reach the exposed port can read, modify, or delete session entries, enabling hijacking of authenticated users and impersonation of administrators without any application\u2011level authentication. This results in potential compromise of confidentiality, integrity, and availability of all active sessions.", "risk_and_exploitability": "The CVSS score of 8.1 categorises this as a high\u2011severity flaw, and the low EPSS value (<1%) indicates a small current exploitation probability; however, the impact of a single exercise is significant. The flaw is not in the CISA KEV catalogue. Exploitation requires simple interaction with the memcached protocol over a publicly reachable port, typically via a machine on the same network or with direct external access. Successful exploitation yields full session control, allowing attackers to impersonate users, elevate privileges to admin, or perform mass session invalidation. No specific privileges are required beyond network connectivity to the port."}}}}, "created": "2026-03-06T14:56:09.251576+00:00", "updated": "2026-04-17T12:30:06.280676+00:00", "vendors": ["wwbn", "wwbn$PRODUCT$avideo"]}
