The Vulnerability One specific dependency was publicly known to have multiple critical vulnerabilities: Ghostscript.  Ghostscript Vulnerability Reports (Snyk) Attack Vectors: Local File Inclusion (LFI): The system processed PDF files without verifying if the uploaded file was actually a PDF. Remote Code Execution (RCE): After a successful injection, attackers could run malicious scripts directly on the server.
