GHSA-9xhq-pm7v-693p phpMyAdmin Cryptographic Vulnerability

• Packagist phpmyadmin/phpmyadmin: >= 4.6, < 4.6.5 → fixed in 4.6.5 • Packagist phpmyadmin/phpmyadmin: >= 4.4, < 4.4.15.9 → fixed in 4.4.15.9 • Packagist phpmyadmin/phpmyadmin: >= 4.0, < 4.0.10.18 → fixed in 4.0.10.18

An issue was discovered in phpMyAdmin. 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.
