{"schemaVersion":3,"id":"CVE-2026-74241","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in Red Hat Quay's external Lightweight Directory Access Protocol (LDAP) authentication handling. When an LDAP referral is returned during authentication, the system does not properly escape the username input. This allows an attacker to inject LDAP filter metacharacters, enabling user-existence oracle attacks at the referral Directory Name (DN). This could also potentially influence which DN is used for password binding in multi-domain Active Directory environments.","dates":{"published":"2026-08-14T22:43:02.202Z","modified":"2026-08-17T15:51:54.577Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0031,"percentile":0.2252,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.12699999999999997,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00183},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.0031,"percentile":0.2252}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00183,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0031,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0031,"percentile":nul
