CVE-2025-49575
Citizen skin vulnerable to stored XSS through multiple system messages
Impact
### Summary 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. ### Details The messages are retrieved using the `plain()` output mode: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/072e4365e9084e4b153eac62d3666566c06f5a49/resources/skins.citizen.commandPalette/components/CommandPaletteFooter.vue#L61-L66 `currentTip` is set to one of these messages: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/072e4365e9084e4b153eac62d3666566c06f5a49/resources/skins.citizen.commandPalette/components/CommandPaletteFooter.vue#L69 `currentTip` is inserted as raw HTML (`vue/no-v-html` should *not* be ignored here): https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/072e4365e9084e4b153eac62d3666566c06f5a49/resources/skins.citizen.commandPalette/components/CommandPaletteFooter.vue#L3-L4 ### PoC 1. Edit `citizen-command-palette-tip-commands`, `citizen-command-palette-tip-users`, `citizen-command-palette-tip-namespace` and `citizen-command-palette-tip-templates` to `<img src="" onerror="alert(1)">` (script tags don't work here due to the way the HTML is inserted) 2. Open the command palette  ### Impact This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right.
