Headline
GHSA-96hh-8hx5-cpw7: October CMS Allows Unprotected SVG Rename in Media Manager
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.
