GHSA-6hr3-44gx-g6wh is a medium-severity (CVSS 5.4) Cross-site Scripting (XSS) vulnerability in phpmyadmin/phpmyadmin. O3 Security confirms whether GHSA-6hr3-44gx-g6wh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Cross-site Scripting vulnerability in drag-and-drop upload of phpMyAdmin
Real-World Exposure
phpmyadmin/phpmyadmin🐘phpmyadmin/phpmyadminReal-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
In phpMyAdmin before 4.9.11 and 5.x before 5.2.1, an authenticated user can trigger Cross-site Scripting (XSS) by uploading a crafted .sql file through the drag-and-drop interface. By disabling the configuration directive $cfg['enable_drag_drop_import'], users will be unable to use the drag and drop upload which would protect against the vulnerability.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | phpmyadmin/phpmyadmin | ≥ 4.3.0&&< 4.9.11 | 4.9.11 |
| 🐘Packagist | phpmyadmin/phpmyadmin | ≥ 5.0&&< 5.2.1 | 5.2.1 |
Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update phpmyadmin/phpmyadmin to 4.9.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6hr3-44gx-g6wh is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-6hr3-44gx-g6wh 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-6hr3-44gx-g6wh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
