CVE-2025-47936
LOWTYPO3 Vulnerable to Server Side Request Forgery via Webhooks
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
TYPO3 is an open source, PHP based web content management system. In versions on the 12.x branch prior to 12.4.31 LTS and the 13.x branch prior to 13.4.2 LTS, Webhooks are inherently vulnerable to Cross-Site Request Forgery (CSRF), which can be exploited by adversaries to target internal resources (e.g., localhost or other services on the local network). While this is not a vulnerability in TYPO3 itself, it may enable attackers to blindly access systems that would otherwise be inaccessible. An administrator-level backend user account is required to exploit this vulnerability. Users should update to TYPO3 version 12.4.31 LTS or 13.4.12 LTS to fix the problem.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms-webhooks. 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 typo3/cms-webhooks to 12.4.31 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-47936 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-2025-47936 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-2025-47936. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-47936 in your dependencies?
O3 detects CVE-2025-47936 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
