CVE-2024-51991: October CMS Allows Unprotected SVG Rename in Media Manager
First published: Mon May 05 2025(Updated: )
### Impact This advisory affects authenticated administrators with sites that have the `media.clean_vectors` configuration enabled. This configuration will sanitize SVG files uploaded using the media manager. This vulnerability allows an authenticated user to bypass this protection by uploading it with a permitted extension (for example, .jpg or .png) and later modifying it to the .svg extension. This vulnerability assumes a trusted user will attack another trusted user and cannot be actively exploited without access to the administration panel and interaction from the other user. ### Patches This issue has been patched in v3.7.5. ### References Credits to: - [Cyber-Wo0dy](https://github.com/Cyber-Wo0dy) ### For more information If you have any questions or comments about this advisory: * Email us at [hello@octobercms.com](mailto:hello@octobercms.com)
