CVE-2026-33477: Filerise

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. In versiosn 2.3.7 through 3.10.0, 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. Version 3.11.0 fixes the issue.

Affected products

• Filerise Filerise: from 2.3.7, before 3.11.0 (fixed in 3.11.0)
