GHSA-59m9-p6cm-94q5 is a medium-severity (CVSS 6.5) vulnerability in in2code/femanager. O3 Security confirms whether GHSA-59m9-p6cm-94q5 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
TYPO3 Extension femanager vulnerable to Broken Access Control
Real-World Exposure
in2code/femanager🐘in2code/femanager🐘in2code/femanagerReal-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
The TYPO3 Extension femanager prior to versions 5.5.2, 6.3.3, and 7.0.1 is vulnerable to broken access control. The usergroup.inList validation can be bypassed resulting in new frontend users created by the extension may be members of groups that are restricted. The vulnerability is only exploitable if the field usergroup is available in the registration form. Versions 5.5.2, 6.3.3, and 7.0.1 contain patches.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for in2code/femanager. 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 in2code/femanager to 7.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-59m9-p6cm-94q5 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-59m9-p6cm-94q5 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-59m9-p6cm-94q5. 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-59m9-p6cm-94q5 in your dependencies?
O3 detects GHSA-59m9-p6cm-94q5 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
