Description
Stirling-PDF 3.0.0 through 3.2.0 contains an authorization bypass vulnerability that allows authenticated users to access other users' stored files by pointing a processing folder at the server storage directory. Attackers can create a folder via POST /api/v1/processing-folders targeting storage/<victimUserId>, list files, and run pipelines to read, modify, or destroy victims' files.
