Authenticated data alteration via token manipulation
Published Sep 10, 2025 · Updated Sep 10, 2025
Improper authorization in Papermerge DMS 3.5.0 through 3.5.3 allows remote authenticated users to alter data via token manipulation. Public records identify the Authorization Token Handler but do not disclose the token field, endpoint, or failed authorization check. A low-privileged account and network access are required; successful exploitation changes protected state and can interrupt service.
