When the user does not specify a blowfish_secret key for encrypting cookies, phpMyAdmin generates one at runtime. A vulnerability was reported where the way this value is created uses a weak algorithm. This could allow an attacker to determine the user's blowfish_secret and potentially decrypt their cookies. All 4.6.x versions (prior to 4.6.5), 4.4.x versions (prior to 4.4.15.9), and 4.0.x versions (prior to 4.0.10.18) are affected.","published":"2016-12-11T02:59:44.553Z","modified":"2026-07-08T12:06:40.568375Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":{"score":0.02002,"percentile":0.79792,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"phpmyadmin/phpmyadmin","fixedVersion":"4.6.5"},{"ecosystem":"Packagist","name":"phpmyadmin/phpmyadmin","fixedVersion":"4.4.15.9"},{"ecosystem":"Packagist","name":"phpmyadmin/phpmyadmin","fixedVersion":"4.0.10.18"}],"fix":null,"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/94524"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201701-32"},{"type":"FIX","url":"https://www.phpmyadmin.net/security/PMASA-2016-58"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T12:06:40.568375Z"}}
