Technical Analysis
CVE-2026-110624 describes a missing authorization vulnerability in Papermerge Core through version 3.5.3. Authenticated users can supply a group_id parameter to the GET /tags/all and GET /document-types/all endpoints to list tags and document types belonging to other groups.

Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected endpoints or monitor usage for suspicious group_id queries. Avoid sharing group UUIDs publicly to reduce risk.
