starcitizentools/citizen-skin allows stored XSS in search no result messages

GHSA-86xf-2mgp-gv3g

Advisory Details

### Summary 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. ### Details The system messages are inserted as raw HTML by the mustache template: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/407052e7069bdeae927d6f1a2a1c9a45b473bf9a/resources/skins.citizen.search/templates/TypeaheadPlaceholder.mustache#L8-L9 ### PoC 1. Edit `citizen-search-noresults-title` and `citizen-search-noresults-desc` to `<img src="" onerror="alert('citizen-search-noresults-title')">` and `<img src="" onerror="alert('citizen-search-noresults-desc')">` (script tags don't work here due to the way the HTML is inserted) 2. Open the search bar and search for a page that doesn't exist to get the "no results" messages to show up ![image](https://github.com/user-attachments/assets/cf2963bc-5c86-4a4d-8574-de92d89d6d81) ![image](https://github.com/user-attachments/assets/44839a7e-c08c-4df9-bd84-0f5863f64163) ### Impact This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right.
