CVE-2025-13827 is a high-severity unrestricted upload of dangerous file types vulnerability in mautic/grapes-js-builder-bundle (composer), affecting versions >= 4.0.0, < 4.4.18. It is fixed in 4.4.18, 5.2.9, 6.0.7. The application accepts file uploads without adequately restricting the file type or content.

Which versions of mautic/grapes-js-builder-bundle are affected by CVE-2025-13827?

mautic/grapes-js-builder-bundle (composer) versions >= 4.0.0, < 4.4.18 is affected.

Is there a fix for CVE-2025-13827?

Is CVE-2025-13827 exploitable, and should I be worried?

Whether CVE-2025-13827 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2025-13827 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

GrapesJsBuilder File Upload allows all file uploads

Arbitrary files can be uploaded via the GrapesJS Builder, as the types of files that can be uploaded are not restricted.

Impact

If the media folder is not restricted from running files this can lead to a remote code execution.

The application accepts file uploads without adequately restricting the file type or content. Typical impact: remote code execution if the uploaded file can be served and executed on the server.

Affected versions

mautic/grapes-js-builder-bundle (>= 4.0.0, < 4.4.18) mautic/grapes-js-builder-bundle (>= 5.0.0, < 5.2.9) mautic/grapes-js-builder-bundle (>= 6.0.0, < 6.0.7)

Security releases

mautic/grapes-js-builder-bundle → 4.4.18 (composer) mautic/grapes-js-builder-bundle → 5.2.9 (composer) mautic/grapes-js-builder-bundle → 6.0.7 (composer)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
