Name of the Vulnerable Software and Affected Versions FileRise versions 2.3.7 through 3.10.0

Description FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. The file snippet endpoint /api/file/snippet.php allows an authenticated user with only read own access to a folder to retrieve snippet content from files uploaded by other users in the same folder. This is a server-side authorization flaw in the read own enforcement for hover previews. The read own access control is bypassed, allowing unauthorized access to file content.

Recommendations FileRise versions 2.3.7 through 3.10.0 should be upgraded to version 3.11.0 or later.
