GHSA-wcmm-28rg-mg3r
GHSA-wcmm-28rg-mg3r is a Improper Input Validation vulnerability in phpmyadmin/phpmyadmin. O3 Security confirms whether GHSA-wcmm-28rg-mg3r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
phpMyAdmin allows remote attackers to obtain installation path via direct request for nonexistent file
Blast Radius
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
phpMyAdmin 2.11.x before 2.11.11.2, and 3.3.x before 3.3.9.1, does not properly handle the absence of the (1) README, (2) ChangeLog, and (3) LICENSE files, which allows remote attackers to obtain the installation path via a direct request for a nonexistent file.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | phpmyadmin/phpmyadmin | ≥ 2.11.0&&< 2.11.11.2 | 2.11.11.2 |

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 2.11.11.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wcmm-28rg-mg3r 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-wcmm-28rg-mg3r 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-wcmm-28rg-mg3r. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-wcmm-28rg-mg3r in your dependencies?
O3 detects GHSA-wcmm-28rg-mg3r across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
