Citizen skin vulnerable to stored XSS through multiple system messages
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

Impact
This impacts wikis where a group has the editinterface but not the editsitejs user right.
