CVE-2023-52083 Information

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.
