CVE-2026-82633Network attack vectorHinoki check available

Authenticated group-data disclosure via unchecked user identifiers

Published Aug 30, 2026 · Updated Aug 30, 2026

Missing authorization in Dolibarr ERP & CRM 10.0.0 through releases before 24.0.0 allows remote authenticated users to read other users' group data. The Users::getGroups REST handler accepts an arbitrary user identifier, fetches that user, and returns group membership data without checking access to the selected user object. Any user with an API key and REST API access can retrieve group names, entity associations, and private notes for other users, including across tenant boundaries.
