Description

The suggestPassword function in js/functions.js in phpMyAdmin 4.0.x before 4.0.10.13, 4.4.x before 4.4.15.3, and 4.5.x before 4.5.4 relies on the Math.random JavaScript function, which makes it easier for remote attackers to guess passwords via a brute-force approach.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyadmin/phpmyadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update phpmyadmin/phpmyadmin to 4.0.10.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2016-1927 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
