GHSA-wrpf-2x8h-82gr
GHSA-wrpf-2x8h-82gr is a security vulnerability in typo3/cms. O3 Security confirms whether GHSA-wrpf-2x8h-82gr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Typo3 Arbitrary File Disclosure in Form Component
Blast Radius
typo3/cmsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Failing to properly validate user input, the form component is susceptible to Arbitrary File Disclosure. A valid backend user account is needed to exploit this vulnerability. Only forms are vulnerable, which contain upload fields.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | typo3/cms | ≥ 6.2.0&&< 6.2.20 | 6.2.20 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms. 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 to 6.2.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wrpf-2x8h-82gr 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-wrpf-2x8h-82gr 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-wrpf-2x8h-82gr. 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-wrpf-2x8h-82gr in your dependencies?
O3 detects GHSA-wrpf-2x8h-82gr across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
