### 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. ``` 'clean_vectors' => true, ``` ### Workarounds If you cannot upgrade for this patch, follow the pervious advice and remove `svg` from the supported file types. ### References - https://github.com/octobercms/october/blob/3.x/config/media.php Credits to: - Faris Krivic - Okan Kurtulus ...

### Impact [CarrierWave::Uploader::ContentTypeAllowlist](https://github.com/carrierwaveuploader/carrierwave/blob/master/lib/carrierwave/uploader/content_type_allowlist.rb) has a Content-Type allowlist bypass vulnerability, possibly leading to XSS. The validation in `allowlisted_content_type?` determines Content-Type permissions by performing a partial match. If the `content_type` argument of `allowlisted_content_type?` is passed a value crafted by the attacker, Content-Types not included in the `content_type_allowlist` will be allowed. In addition, by setting the Content-Type configured by the attacker at the time of file delivery, it is possible to cause XSS on the user's browser when the uploaded file is opened. ### Patches Upgrade to [3.0.5](https://rubygems.org/gems/carrierwave/versions/3.0.5) or [2.2.5](https://rubygems.org/gems/carrierwave/versions/2.2.5). ### Workarounds When validating with `allowlisted_content_type?` in [CarrierWave::Uploader::ContentTypeAllowlist](https:...
