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.

Affected: Packagist: starcitizentools/citizen-skin

### Summary Short descriptions set via the [ShortDescription extension](https://www.mediawiki.org/wiki/Extension:ShortDescription) are inserted as raw HTML by the Citizen skin, allowing any user to insert arbitrary HTML into the DOM by editing a page.

### Details The `shortdesc` property, which contains unsanitized user input, is retrieved from the OutputPage and returned as the tagline: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/0d8a44011e02a081618359a1e90f462478e807aa/includes/Components/CitizenComponentPageHeading.php#L249-L251 The tagline is then provided to the template data: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/0d8a44011e02a081618359a1e90f462478e807aa/includes/Components/CitizenComponentPageHeading.php#L270-L275 The template then inserts the tagline into raw HTML without doing any escaping: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/0d8a44011e02a081618359a1e90f462478e807aa/templates/PageHeading.mustache#L12
