Name of the Vulnerable Software and Affected Versions: rails-html-sanitizer version 1.6.0 Description: A possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags where the "math" and "style" elements are both explicitly allowed. This issue is relevant when used with Rails >= 7.1.0. The default configuration is to disallow these elements, and code is only impacted if allowed tags are being overridden. Recommendations: For rails-html-sanitizer version 1.6.0, upgrade to version 1.6.1 to fix the vulnerability. As a temporary workaround, consider removing "math" or "style" from the overridden allowed tags, or downgrade sanitization to HTML4 by configuring `config.action view.sanitizer vendor` and `config.action text.sanitizer vendor` accordingly.

Name of the Vulnerable Software and Affected Versions: rails-html-sanitizer version 1.6.0 Description: There is a possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer when used with Rails >= 7.1.0. This issue may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags where the "math", "mtext", "table", and "style" elements are allowed and either "mglyph" or "malignmark" are allowed. Recommendations: For rails-html-sanitizer version 1.6.0, upgrade to version 1.6.1 to fix the vulnerability. Alternatively, remove "mglyph" and "malignmark" from the overridden allowed tags or downgrade sanitization to HTML4.

Name of the Vulnerable Software and Affected Versions: rails-html-sanitizer versions 1.6.0 Description: The issue is related to a possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer when used with Rails >= 7.1.0. This vulnerability may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags for the "noscript" element. Recommendations: For rails-html-sanitizer version 1.6.0, upgrade to version 1.6.1 to fix the vulnerability. As a temporary workaround, consider removing "noscript" from the overridden allowed tags or downgrading sanitization to HTML4.

Name of the Vulnerable Software and Affected Versions: rails-html-sanitizer version 1.6.0 Description: The issue is related to a possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer when used with Rails >= 7.1.0 and Nokogiri < 1.15.7, or 1.16.x < 1.16.8. This vulnerability may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags with both "math" and "style" elements or both "svg" and "style" elements. Recommendations: For rails-html-sanitizer version 1.6.0, upgrade to version 1.6.1 to fix the vulnerability. As a temporary workaround, consider removing "style" from the overridden allowed tags, or remove "math" and "svg" from the overridden allowed tags, or downgrade sanitization to HTML4. Alternatively, independently upgrade Nokogiri to v1.15.7 or >= 1.16.8.

Name of the Vulnerable Software and Affected Versions: rails-html-sanitizer version 1.6.0 Description: A possible XSS vulnerability exists with certain configurations of Rails::HTML::Sanitizer when used with Rails >= 7.1.0. This vulnerability may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags where the `style` element is explicitly allowed and the `svg` or `math` element is not allowed. Recommendations: For rails-html-sanitizer version 1.6.0, upgrade to version 1.6.1 to fix the vulnerability. As a temporary workaround, consider removing `style` from the overridden allowed tags or downgrading sanitization to HTML4.

**Name of the Vulnerable Software and Affected Versions** Rocket.Chat versions prior to 6.10.1 **Description** A Server-Side Request Forgery (SSRF) affects Rocket.Chat’s Twilio webhook endpoint. SSRF occurs when an application makes requests to an unintended location, potentially allowing an attacker to access internal systems. Approximately 1781 internet-exposed instances have been identified. The issue allows attackers to redirect requests, potentially exposing sensitive data. The vulnerable component is the Twilio webhook endpoint, specifically the handling of requests to this endpoint. The `webhook` functionality is susceptible to manipulation, allowing an attacker to control the destination of server-side requests. **Recommendations** Versions prior to 6.10.1 should be updated to version 6.10.1 or later.

**Name of the Vulnerable Software and Affected Versions** GitLab CE/EE versions 6.6 through 15.5.7 GitLab CE/EE versions 15.6 through 15.6.4 GitLab CE/EE versions 15.7 through 15.7.2 **Description** An issue has been discovered in GitLab CE/EE that affects various versions. The problem is related to a regex issue in the submodule URL parser, which can be exploited by an attacker to cause a Denial of Service on a GitLab instance. **Recommendations** For versions 6.6 through 15.5.7, update to version 15.5.7 or later to resolve the issue. For versions 15.6 through 15.6.4, update to version 15.6.4 or later to resolve the issue. For versions 15.7 through 15.7.2, update to version 15.7.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the submodule URL parser to minimize the risk of exploitation.
