Summary
Drupal Malicious file upload with filenames stating with dot
Drupal 8 core's file_save_upload() function does not strip the leading and trailing dot ('.') from filenames, like Drupal 7 did.
Users with the ability to upload files with any extension in conjunction with contributed modules may be able to use this to upload system files such as .htaccess in order to bypass protections afforded by Drupal's default .htaccess file.
After this fix, file_save_upload() now trims leading and trailing dots from filenames.
Impact
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.

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.

Frequently Asked Questions
- What is GHSA-58XV-7H9R-MX3C? GHSA-58XV-7H9R-MX3C is a medium-severity unrestricted upload of dangerous file types vulnerability in drupal/drupal (composer), affecting versions >= 8.0.0, < 8.7.11. It is fixed in 8.7.11, 8.8.1. The application accepts file uploads without adequately restricting the file type or content.
- Which versions of drupal/drupal are affected by GHSA-58XV-7H9R-MX3C? drupal/drupal (composer) versions >= 8.0.0, < 8.7.11 is affected.
- Is there a fix for GHSA-58XV-7H9R-MX3C? Yes. GHSA-58XV-7H9R-MX3C is fixed in 8.7.11, 8.8.1. Upgrade to this version or later.
- Is GHSA-58XV-7H9R-MX3C exploitable, and should I be worried? Whether GHSA-58XV-7H9R-MX3C 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 GHSA-58XV-7H9R-MX3C 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.
