## Summary There is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer. This is due to an incomplete fix of CVE-2022-32209. - Versions affected: ALL - Not affected: NONE - Fixed versions: 1.4.4 ## Impact A possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both "select" and "style" elements. Code is only impacted if allowed tags are being overridden using either of the following two mechanisms: 1. Using the Rails configuration `config.action_view.sanitized_allow_tags=`: ```ruby # In config/application.rb config.action_view.sanitized_allowed_tags = ["select", "style"] ``` (see https://guides.rubyonrails.org/configuring.html#configuring-action-view) 2. Using the class method `Rails::Html::SafeListSanitizer.allowed_tags=`: ```ruby # class-level option Rails::Html::SafeListSanitizer...

Applications may be doing this in four different ways: 1. using application configuration: ```ruby # In config/application.rb config.action_view.sanitized_allowed_tags = ["math", "style"] # or config.action_view.sanitized_allowed_tags = ["svg", "style"] ``` see https://guides.rubyonrails.org/configuring.html#configuring-action-view 2. using a `:tags` option to the Action View helper `sanitize`: ``` <%= saniti...

### Problem Due to a parsing issue in the upstream package [`masterminds/html5`](https://packagist.org/packages/masterminds/html5), malicious markup used in a sequence with special HTML CDATA sections cannot be filtered and sanitized. This allows bypassing the cross-site scripting mechanism of [`typo3/html-sanitizer`](https://packagist.org/packages/typo3/html-sanitizer). Besides that, the upstream package `masterminds/html5` provides HTML raw text elements (`script`, `style`, `noframes`, `noembed` and `iframe`) as DOMText nodes, which were not processed and sanitized further. None of the mentioned elements were defined in the default builder configuration, that's why only custom behaviors, using one of those tag names, were vulnerable to cross-site scripting. ### Solution Update to `typo3/html-sanitizer` versions 1.5.0 or 2.1.1 that fix the problem described.

Impact of cloud migration and shift to remote work evident in new report

A vulnerability has been identified in Mendix Email Connector (All versions < V2.0.0). Affected versions of the module improperly handle access control for some module entities. This could allow authenticated remote attackers to read and manipulate sensitive information.
