Description
Multiple cross-site scripting (XSS) vulnerabilities in phpMyAdmin 3.4.x before 3.4.8 allow remote attackers to inject arbitrary web script or HTML via (1) a crafted database name, related to the Database Synchronize panel; (2) a crafted database name, related to the Database rename panel; (3) a crafted SQL query, related to the table overview panel; (4) a crafted SQL query, related to the view creation dialog; (5) a crafted column type, related to the table search dialog; or (6) a crafted column type, related to the create index dialog.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyadmin/phpmyadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update phpmyadmin/phpmyadmin to 3.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9j9h-cpgc-8356 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-9j9h-cpgc-8356 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-9j9h-cpgc-8356. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
