Adobe Acrobat allows hidden data to remain in printed PDFs

Original description
The application allows PDF JavaScript and document/print actions (such as WillPrint/DidPrint) to update form fields, annotations, or optional content groups (OCGs) immediately before or after redaction, encryption, or printing. These script‑driven updates are not fully covered by the existing redaction, encryption, and printing logic, which, under specific document structures and user workflows, may cause a small amount of sensitive content to remain unremoved or unencrypted as expected, or result in printed output that slightly differs from what was reviewed on screen.
