SSH servers implemented with Apache\nMINA SSHD are affected only if they use sshd-ldap and do configure it to be used for password of public key authentication.\n\nOther Apache MINA SSHD servers are not affected.\n\n\n\n\nLack of escaping LDAP filter metacharacters enabled successful authentication with username \"*\" and password \"*\".\n\n\n\n\nUsers are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue by properly escaping filter parameters according to RFC 4515.","dates":{"published":"2026-09-30T09:43:47.477Z","modified":"2026-09-30T14:30:10.327Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.1,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
