CVE-2026-110624
Papermerge Core through 3.5.3 contains a missing authorization vulnerability that allows authenticated users to list other groups' tags and document types by supplying a group_id parameter.
Does this matter?
Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.
Description
Papermerge Core through 3.5.3 contains a missing authorization vulnerability that allows authenticated users to list other groups' tags and document types by supplying a group_id parameter. Attackers who know a group's UUID can query GET /tags/all or GET /document-types/all, which skip the user_belongs_to check, to disclose metadata of groups they do not belong to.
