Description
This security bulletin contains information about 1 security vulnerability.
1) Improper access control (CVE-ID: CVE-2026-31872)
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to improper access control in the protectedFields class-level permission enforcement when processing query WHERE clauses and sort parameters that use dot-notation. A remote attacker can send specially crafted queries or sort parameters using dot-notation to disclose sensitive information.
This affects both MongoDB and PostgreSQL deployments and enables a binary oracle attack to enumerate protected field values.
