CVE-2026-85055Network attack vectorHinoki check available

Authenticated field disclosure via filter oracle

Published Sep 22, 2026 · Updated Sep 22, 2026

Improper authorization in Twenty before 2.22.0 allows remote authenticated users to infer denied field values through API filters. GraphQL, REST, relation, and persisted-view filter builders evaluate unreadable columns without first enforcing field-level read permission, while totalCount and row presence expose each predicate result. A workspace member or API key needs object-read access, and the oracle reveals only records permitted by the principal's row-level policy.
