Unauthorized draft publication via recordless permission check
Published Dec 6, 2021 · Updated Aug 4, 2024
Missing authorization in Invenio Drafts Resources before 0.13.7 and 0.14.0 through 0.14.5 allows remote authenticated users to publish others' drafts. The publish() service method checks the publish permission without passing the target draft, causing RecordOwners() to default to any authenticated user. The attacker must know a valid draft identifier, and exploitation publishes but does not modify the victim's record or change its visibility.
