Description
Multiple cross-site scripting (XSS) vulnerabilities in 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 allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) a crafted table name that is mishandled during privilege checking in table_row.phtml, (2) a crafted mysqld log_bin directive that is mishandled in log_selector.phtml, (3) the Transformation implementation, (4) AJAX error handling in js/ajax.js, (5) the Designer implementation, (6) the charts implementation in js/tbl_chart.js, or (7) the zoom-search implementation in rows_zoom.phtml.

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 CVE-2016-5733 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 CVE-2016-5733 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 CVE-2016-5733. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
