A bounded cost should be enforced to avoid a server DOS.\n\n\n\nThis issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.\n\n\n\nUsers are recommended to upgrade to version 2.1.9, which fixes the issue.","dates":{"published":"2026-10-02T10:03:48.296Z","modified":"2026-10-05T18:47:17.198Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
