GHSA-wm9c-vcv2-vpqc
MEDIUMGHSA-wm9c-vcv2-vpqc is a medium-severity (CVSS 5.3) Information Exposure vulnerability in phpmyadmin/phpmyadmin. O3 Security confirms whether GHSA-wm9c-vcv2-vpqc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
phpMyAdmin 4.0.x before 4.0.10.16, 4.4.x before 4.4.15.7, and 4.6.x before 4.6.3 allows remote attackers to obtain sensitive information via vectors involving (1) an array value to FormDisplay.php, (2) incorrect data to validate.php, (3) unexpected data to Validator.php, (4) a missing config directory during setup, or (5) an incorrect OpenID identifier data type, which reveals the full path in an error message.

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 4.0.10.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wm9c-vcv2-vpqc 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-wm9c-vcv2-vpqc 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-wm9c-vcv2-vpqc. 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-wm9c-vcv2-vpqc in your dependencies?
O3 detects GHSA-wm9c-vcv2-vpqc across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
