CVE-2023-44383 [MEDIUM] CWE-79 October CMS stored XSS by authenticated backend user with improper configuration
October CMS stored XSS by authenticated backend user with improper configuration
### Impact
A user with access to the media manager that stores SVG files could create a stored XSS attack against themselves and any other user with access to the media manager when SVG files are supported.
SVG files are supported by default in v3 for convenience; however, this has resulted in multiple mistaken vulnerability reports from security researchers. As per the documentation, if a backend user is not trusted, the advice is to remove the `svg` extension from the list of supported file types.
### Patches
The issue has been patched in v3.5.2 by including an SVG sanister. It is enabled by default for new installations but must be enabled for existing sites in the **config/media.php** file.
