{"id":"AZL-95702","summary":"CVE-2026-14672 affecting package postgresql 16.14-1","details":"Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count.  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.","modified":"2026-09-02T06:51:55Z","published":"2026-08-13T13:17:44Z","upstream":["CVE-2026-14672"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-14672"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"16.14-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95702.json"}}],"schema_version":"1.9.0"}
