Description
phpMyFAQ before 4.1.2 contains a missing authorization vulnerability in the DELETE /admin/api/content/tags/{tagId} endpoint that allows any authenticated user to delete tags. Any logged-in user, including regular frontend users, can delete arbitrary tags by sending a DELETE request with a valid session cookie, resulting in permanent data loss and disruption of FAQ organization.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyfaq/phpmyfaq. 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 phpmyfaq/phpmyfaq to 4.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-46365 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-2026-46365 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-2026-46365. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
