PDF URI references command interpreter path high PDF_DANGEROUS_URI_COMMANDPDF contains a /URI action whose target uses a mailto/path traversal shape and references a command interpreter or scripting host. This is not a normal web link and matches legacy PDF command execution/dropper lures.

External URI low PDF_URIPDF contains an external URL action

Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
