Which packages are affected by CVE-2024-24751?

CVE-2024-24751 affects the following packages: derhansen/sf_event_mgt (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2024-24751?

Update derhansen/sf_event_mgt to 7.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-24751 is resolved across your whole dependency graph.

How do I detect CVE-2024-24751 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for derhansen/sf_event_mgt. 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.

How do I mitigate CVE-2024-24751 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2024-24751?

O3 pinpoints whether CVE-2024-24751 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-24751 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-24751 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-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

sf_event_mgt is an event management and registration extension for the TYPO3 CMS based on ExtBase and Fluid. In affected versions the existing access control check for events in the backend module got broken during the update of the extension to TYPO3 12.4, because the RedirectResponse from the $this->redirect() function was never handled. This issue has been addressed in version 7.4.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
