Summary: Cross-site Scripting in the Flamingo theme manager

Details: ### Impact We found a possible XSS vector in the `FlamingoThemesCode.WebHomeSheet` wiki page related to the "newThemeName" form field. ### Patches The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3. ### Workarounds The easiest workaround is to edit the wiki page `FlamingoThemesCode.WebHomeSheet` (with wiki editor) and change the line ``` <input type="hidden" name="newThemeName" id="newThemeName" value="$request.newThemeName" /> ``` into ``` <input type="hidden" name="newThemeName" id="newThemeName" value="$escapetool.xml($request.newThemeName)" /> ``` ### References * https://jira.xwiki.org/browse/XWIKI-19294 * https://github.com/xwiki/xwiki-platform/commit/bd935320bee3c27cf7548351b1d0f935f116d437 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security mailing list](mailto:[email protected])
