### 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:...

CarrierWave is a solution for file uploads for Rails, Sinatra and other Ruby web frameworks. CarrierWave 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. This issue has been patched in versions 2.2.5 and 3.0.5.

raptor-web is a CMS for game server communities that can be used to host information and keep track of players. In version 0.4.4 of raptor-web, it is possible to craft a malicious URL that will result in a reflected cross-site scripting vulnerability. A user controlled URL parameter is loaded into an internal template that has autoescape disabled. This is a cross-site scripting vulnerability that affects all deployments of `raptor-web` on version `0.4.4`. Any victim who clicks on a malicious crafted link will be affected. This issue has been patched 0.4.4.1.

The uninstaller in Fortra Digital Guardian Agent versions prior to 7.9.4 suffers from a cross site scripting vulnerability. Additionally, the Agent Uninstaller handles sensitive data insecurely and caches the Uninstall key in memory. This key can be used to stop or uninstall the application. This allows a locally authenticated attacker with administrative privileges to disable the application temporarily or even remove the application from the system completely.
