Description

Papermerge Core through 3.5.3 contains a missing authorization vulnerability that allows authenticated users to manipulate other users' pages because page management and OCR endpoints skip has_node_perm checks. Attackers knowing page UUIDs can call /pages/, /pages/move, or /pages/extract to rotate, delete, or extract victims' pages, and trigger OCR via /tasks/ocr.
