Technical details
The vulnerability exists in the form submission handler where JSON arrays representing uploaded files are processed with insufficient validation. While numeric ID checks are performed, client-supplied filenames and display names are accepted without sanitization, enabling metadata tampering and potential path traversal through functions like getFilePath(). An attacker with network access to submit forms can exploit this to manipulate or access file metadata and paths across sessions.
