An issue was discovered in Mattermost Server before 4.2.0, 4.1.1, and 4.0.5. E-mail templates can have a field in which HTML content is not neutralized.

OMERO.web provides a web based client and plugin infrastructure. In versions prior to 5.11.0, a variety of templates do not perform proper sanitization through HTML escaping. Due to the lack of sanitization and use of ``jQuery.html()``, there are a whole host of cross-site scripting possibilities with specially crafted input to a variety of fields. This issue is patched in version 5.11.0. There are no known workarounds aside from upgrading.

dom-expressions is a Fine-Grained Runtime for Performant DOM Rendering. In affected versions the use of javascript's `.replace()` opens up to potential Cross-site Scripting (XSS) vulnerabilities with the special replacement patterns beginning with `$`. Particularly, when the attributes of `Meta` tag from solid-meta are user-defined, attackers can utilise the special replacement patterns, either `$'` or `$\`` to achieve XSS. The solid-meta package has this issue since it uses `useAffect` and context providers, which injects the used assets in the html header. "dom-expressions" uses `.replace()` to insert the assets, which is vulnerable to the special replacement patterns listed above. This effectively means that if the attributes of an asset tag contained user-controlled data, it would be vulnerable to XSS. For instance, there might be meta tags for the open graph protocol in a user profile page, but if attackers set the user query to some payload abusing `.replace()`, then they could execute arbitrary javascript in the victim's web browser. Moreover, it could be stored and cause more problems. This issue has been addressed in version 0.39.5 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to version 4.0.0-beta.380, the tags page allows users to search for tags. If the search does not return any results, the query gets reflected on the error modal, which leads to cross-site scripting. Version 4.0.0-beta.380 fixes the issue.

In the Pro and Enterprise versions of GTranslate < 2.8.65, the gtranslate_request_uri_var function runs at the top of all pages and echoes out the contents of $_SERVER['REQUEST_URI']. Although this uses addslashes, and most modern browsers automatically URLencode requests, this plugin is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below, or in cases where an attacker is able to modify the request en route between the client and the server, or in cases where the user is using an atypical browsing solution.

PrestaShop is an open source e-commerce web application. Versions prior to 1.7.8.10, 8.0.5, and 8.1.1 are vulnerable to cross-site scripting through the `isCleanHTML` method. Versions 1.7.8.10, 8.0.5, and 8.1.1 contain a patch. There are no known workarounds.

Critters versions 0.0.17-0.0.19 have an issue when parsing the HTML, which leads to a potential cross-site scripting (XSS) bug. We recommend upgrading to version 0.0.20 of the extension. 

An issue was discovered in GitLab Community and Enterprise Edition before 11.8.9, 11.9.x before 11.9.10, and 11.10.x before 11.10.2. It has Improper Encoding or Escaping of Output. The branch name on new merge request notification emails isn't escaped, which could potentially lead to XSS issues.

Dell EMC Data Protection Central, versions 19.1 through 19.7, contains a Host Header Injection vulnerability. A remote unauthenticated attacker may potentially exploit this vulnerability by injecting arbitrary \u2018Host\u2019 header values to poison a web cache or trigger redirections.

A malicious page could have used the type attribute of an OBJECT tag to override the default browser behavior when encountering a web resource served without a content-type. This could have contributed to an XSS on a site that unsafely serves files without a content-type header. This vulnerability affects Firefox < 144, Firefox ESR < 140.4, Thunderbird < 144, and Thunderbird < 140.4.
