Previously, media manager files were only sanitized on upload, not on renaming, which could have allowed a stored XSS attack.

Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
Description
Winter is a free, open-source content management system. Prior to 1.2.4, users with the `media.manage_media` permission can upload files to the Media Manager and rename them after uploading. Previously, media manager files were only sanitized on upload, not on renaming, which could have allowed a stored XSS attack. This issue has been patched in v1.2.4.
