Miggo AIRoot Cause Analysis

The vulnerability stems from missing HTML encoding in backend filelink content element descriptions. The security bulletin explicitly references adding htmlSpecialChars to tt_content.uploads.20.itemRendering.20.2 configuration, indicating the rendering method for upload items was previously vulnerable. The tslib_content_uploads class handles content element rendering, and its item rendering method would be responsible for outputting unescaped user-controlled description fields prior to the patch.
