starcitizentools/citizen-skin allows stored XSS in preference menu heading messages

發布日:2025/6/13修改日:2025/6/13

描述

### Summary Various preferences messages are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. ### Details The `innerHtml` of the label div is set to the `textContent` of the label, essentially unsanitizing the system messages: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/407052e7069bdeae927d6f1a2a1c9a45b473bf9a/resources/skins.citizen.preferences/addPortlet.polyfill.js#L18 ### PoC 1. Edit `citizen-feature-custom-font-size-name` (or any other message displayed in a heading in the preferences menu) to `<img src="" onerror="alert('citizen-feature-custom-font-size-name')">` (script tags don't work here due to the way the HTML is inserted) 2. Open the preferences menu ![image](https://github.com/user-attachments/assets/b75f100d-09cc-443c-b635-e9d6ab48d133)
