Which packages are affected by CVE-2024-51734?

CVE-2024-51734 affects the following packages: accesscontrol (PyPI), zope (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2024-51734?

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.

How do I detect CVE-2024-51734 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for accesscontrol, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-51734 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-2024-51734?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-51734 can be triaged on real exposure rather than presence alone.

Is CVE-2024-51734 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-51734 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.

What is the EPSS score for CVE-2024-51734?

CVE-2024-51734 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 37th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-51734?

CVE-2024-51734 is classified as CWE-284 (CWE-284). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-51734 published, and has it been updated?

CVE-2024-51734 was published on November 4, 2024 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
