CVE-2024-47055 has a CVSS score of 4.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-47055?

CVE-2024-47055 affects the following packages: mautic/core (Packagist), mautic/core (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2024-47055?

Update mautic/core to 5.2.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47055 is resolved across your whole dependency graph.

How do I detect CVE-2024-47055 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mautic/core. 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-2024-47055 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-2024-47055?

O3 pinpoints whether CVE-2024-47055 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-2024-47055 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-47055 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-2024-47055?

CVE-2024-47055 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 11th 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.

When was CVE-2024-47055 published, and has it been updated?

CVE-2024-47055 was published on May 28, 2025 and was last updated on April 10, 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

SummaryThis advisory addresses a security vulnerability in Mautic related to the segment cloning functionality. This vulnerability allows any authenticated user to clone segments without proper authorization checks.

Insecure Direct Object Reference (IDOR) / Missing Authorization: A missing authorization vulnerability exists in the cloneAction of the segment management. This allows an authenticated user to bypass intended permission restrictions and clone segments even if they lack the necessary permissions to create new ones.

MitigationUpdate Mautic to a version that implements proper authorization checks for the cloneAction within the ListController.php. Ensure that users attempting to clone segments possess the appropriate creation permissions.
