{"id":"JLSEC-2026-605","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":"2026-06-08T14:00:04.313763785Z","published":"2026-06-08T13:54:13.679Z","upstream":["CVE-2026-6478"],"database_specific":{"sources":[{"id":"CVE-2026-6478","published":"2026-05-14T14:16:25.463Z","imported":"2026-06-08T13:34:09.866Z","modified":"2026-05-18T15:03:55.670Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-6478","database_specific":{"status":"Analyzed"},"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6478"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2026-6478/"}],"affected":[{"package":{"name":"LibPQ_jll","ecosystem":"Julia","purl":"pkg:julia/LibPQ_jll?uuid=08be9ffa-1c94-5ee5-a977-46a84ec9b350"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"16.14.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-605.json"}}],"schema_version":"1.7.5"}
