Description
Zope AccessControl provides a general security framework for use in Zope. In affected versions anonymous users can delete the user data maintained by an AccessControl.userfolder.UserFolder which may prevent any privileged access. This problem has been fixed in version 7.2. Users are advised to upgrade. Users unable to upgrade may address the issue by adding data__roles__ = () to AccessControl.userfolder.UserFolder.

|---|---|---|---|
| 🐍PyPI | accesscontrol | all versions | 7.2 |
| 🐍PyPI | zope | all versions | 5.11.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for accesscontrol. 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 accesscontrol to 7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-51734 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-2024-51734 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-2024-51734. 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-2024-51734 in your dependencies?
O3 detects CVE-2024-51734 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
