CVE-2026-111645
MrDoc through 1.1.1 contains a missing object-level authorization vulnerability in the ImportLocalDoc API that allows authenticated users to modify other users' documents and projects.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
MrDoc through 1.1.1 contains a missing object-level authorization vulnerability in the ImportLocalDoc API that allows authenticated users to modify other users' documents and projects. Attackers can send PUT requests with arbitrary sort_data document ids to publish private drafts and reparent documents, or POST with arbitrary top_doc ids to inject documents.
