Protected field disclosure via unrestricted where queries
Published Apr 26, 2023 · Updated Feb 3, 2025
Information disclosure in Payload before 1.7.0 allows remote attackers to infer protected field values through crafted where queries. The query builder accepted filters against hidden or access-restricted fields and revealed value matches through differing query results. The attacker needs access to documents in a readable collection, and repeated guesses disclose hidden data without directly returning the field.
