This requires the probed user to have a non-default scram_iterations count, because the authentication challenge for a nonexistent user reports the default scram_iterations.  Within major versions 16-18, minor versions before PostgreSQL 18.6, 17.11, and 16.15 are affected.  Versions before PostgreSQL 16 are unaffected.","published":"2026-08-13T13:17:45.000Z","lastModified":"2026-08-29T23:17:15.000Z","status":"Modified","sourceIdentifier":"f86ef6dc-4d3a-42ad-8f28-e6d5547a5007","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-204"],"affected":["postgresql/postgresql"],"epss":{"score":0.00394,"percentile":0.33369,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.39%).
