{"id":"AZL-86819","summary":"CVE-2026-6478 affecting package postgresql for versions less than 16.14-1","details":"Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate.  This does not affect scram-sha-256 passwords, the default in all supported releases.  However, current databases may have MD5-hashed passwords originating in upgrades from PostgreSQL 13 or earlier.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.","modified":"2026-08-28T17:48:00.277441803Z","published":"2026-05-14T14:16:25Z","upstream":["CVE-2026-6478"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6478"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.14-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86819.json"}}],"schema_version":"1.9.0"}
