GHSA-r326-mp8g-6xfc

HIGH

GHSA-r326-mp8g-6xfc is a high-severity (CVSS 7.5) CWE-254 vulnerability in phpmyadmin/phpmyadmin. O3 Security confirms whether GHSA-r326-mp8g-6xfc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

An issue was discovered in phpMyAdmin. Due to the limitation in URL matching, it was possible to bypass the URL white-list protection. 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.

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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update phpmyadmin/phpmyadmin to 4.6.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r326-mp8g-6xfc 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-r326-mp8g-6xfc is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-r326-mp8g-6xfc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
