CVE-2025-48494Network attack vector

Stored XSS via HTML-rendered encrypted filenames

Published Jun 2, 2025 · Updated Jun 2, 2025

Stored XSS in Gokapi before 2.0.0 allows remote authenticated users to execute JavaScript in another user's browser via a filename. The decryptFileEntry path passes a decrypted filename to DataTables as HTML instead of assigning text content, causing embedded markup to be interpreted. Exploitation requires end-to-end encryption, multiple authenticated users, and a victim who opens the upload list.
