Browser script execution via unsanitized PDF metadata

Published Dec 29, 2025 · Updated Dec 29, 2025

Stored XSS in MachSol MachPanel 8.0.32 allows remote attackers to execute scripts in a user's browser through a crafted PDF. The support-ticket upload flow accepts script-bearing PDF metadata and later serves the uploaded file without neutralizing that content. A user must access the uploaded file, and the reported consequence is confined to script execution in that user's browser context.
