## Technical details

The vulnerability is a missing authentication check in the /uploads endpoint handling. Because Express.js serves static files from the public/ directory before the hasAuth-guarded /uploads mount point, an attacker can bypass authentication by directly requesting attachment paths with a valid ObjectId and filename. No special privileges or user interaction required beyond network access and knowledge of ticket identifiers.
