GHSA-8m97-xc46-rw9w
HIGHGHSA-8m97-xc46-rw9w is a high-severity (CVSS 7.5) CWE-254 vulnerability in phpmyadmin/phpmyadmin. O3 Security confirms whether GHSA-8m97-xc46-rw9w is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
libraries/common.inc.php 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 does not use a constant-time algorithm for comparing CSRF tokens, which makes it easier for remote attackers to bypass intended access restrictions by measuring time differences.

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 4.0.10.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8m97-xc46-rw9w 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-8m97-xc46-rw9w 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-8m97-xc46-rw9w. 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-8m97-xc46-rw9w in your dependencies?
O3 detects GHSA-8m97-xc46-rw9w across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
