XWiki Platform Attachment UI provides a macro to easily upload and select attachments for XWiki Platform, a generic wiki platform. Starting with version 14.0-rc-1 and prior to 14.4-rc-1, it's possible to store JavaScript in an attachment name, which will be executed by anyone trying to move the corresponding attachment. This issue has been patched in XWiki 14.4-rc-1. As a workaround, one may copy `moveStep1.vm` to `webapp/xwiki/templates/moveStep1.vm` and replace vulnerable code with code from the patch.

GHSA-9r9j-57rf-f6vj — XWiki Platform Attachment UI vulnerable to cross-site scripting in the move attachment form

Affected: Maven: org.xwiki.platform:xwiki-platform-attachment-ui

### Impact

It's possible to store JavaScript in an attachment name, which will be executed by anyone trying to move the corresponding attachment.

For example, an attachment with name `><img src=1 onerror=alert(1)>.jpg` will execute the alert.

### Patches This issue has been patched in XWiki 14.4RC1.

### Workarounds It is possible to fix the vulnerability by copying [moveStep1.vm](https://raw.githubusercontent.com/xwiki/xwiki-platform/xwiki-platform-14.0-rc-1/xwiki-platform-core/xwiki-platform-attachment/xwiki-platform-attachment-api/src/main/resources/templates/attachment/moveStep1.vm) to `webapp/xwiki/templates/moveStep1.vm` and replace

``` #set($titleToDisplay = $services.localization.render('attachment.move.title', [$attachment.name, $escapetool.xml($doc.plainTitle), $doc.getURL()])) ```

``` #set($titleToDisplay = $services.localization.render('attachment.move.title', [ $escapetool.xml($attachment.name), $escapetool.xml($doc.plainTitle), $escapetool.xml($doc.getURL()) ])) ```

See the corresponding [patch](https://github.com/xwiki/xwiki-platform/commit/fbc4bfbae4f6ce8109addb281de86a03acdb9277).
