CVE-2026-111350
Papermark through 0.22.0 contains a missing authorization vulnerability in the data room viewer group API that allows authenticated users to delete other teams' viewer groups and share links.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
Description
