Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Citizen from 3.3.0 to 3.9.0 are vulnerable to stored cross-site scripting in the sticky header button message handling. In stickyHeader.js the copyButtonAttributes function assigns innerHTML from a source element’s textContent when copying button labels. This causes escaped HTML in system message content (such as citizen-share, citizen-view-history, citizen-view-edit, and nstab-talk) to be interpreted as HTML in the sticky header, allowing injection of arbitrary script by a user with the ability to edit interface messages. The vulnerability allows a user with the editinterface right but without the editsitejs right (by default the sysop group has editinterface but may not have editsitejs) to execute arbitrary JavaScript in other users’ sessions, enabling unauthorized access to sensitive data or actions. The issue is fixed in 3.9.0.
Short Description is a MediaWiki extension that provides local short description support. In version 4.0.0, short descriptions are not properly sanitized before being inserted as HTML using mw.util.addSubtitle, allowing any user to insert arbitrary HTML into the DOM by editing a page. This issue has been patched in version 4.0.1.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. From versions 1.9.4 to before 3.4.0, short descriptions set via the ShortDescription extension are inserted as raw HTML by the Citizen skin, allowing any user to insert arbitrary HTML into the DOM by editing a page. This issue has been patched in version 3.4.0.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. From versions 1.9.4 to before 3.4.0, page descriptions are inserted into raw HTML without proper sanitization by the Citizen skin when using the old search bar. Any user with page editing privileges can insert cross-site scripting (XSS) payloads into the DOM for other users who are searching for specific pages. This issue has been patched in version 3.4.0.
TabberNeue is a MediaWiki extension that allows the wiki to create tabs. Starting in version 3.0.0 and prior to version 3.1.1, any user can insert arbitrary HTMLinto the DOM by inserting a payload into any allowed attribute of the `<tabber>` tag. Version 3.1.1 contains a patch for the bug.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. The citizen-search-noresults-title and citizen-search-noresults-desc system messages are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This vulnerability is fixed in 3.3.1.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Various date messages returned by `Language::userDate` are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right. This vulnerability is fixed in 3.3.1.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. All system messages in menu headings using the Menu.mustache template are inserted as raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right. This vulnerability is fixed in 3.3.1.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Multiple system messages are inserted into the CommandPaletteFooter as raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right. This vulnerability is fixed in 3.3.1.
Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Various preferences messages are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This vulnerability is fixed in 3.3.1.
TabberNeue is a MediaWiki extension that allows the wiki to create tabs. Prior to 2.7.2, TabberTransclude.php doesn't escape the user-supplied page name when outputting, so an XSS payload as the page name can be used here. This vulnerability is fixed in 2.7.2.
