NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql16 package and not the postgresql16 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

Incomplete tracking in PostgreSQL of changes to role membership, role attributes, and database ownership allows a query to continue using cached row-level security policies after those changes require a different policy, via plan reuse. Stale policies continue until some other event invalidates the cache or connection termination ends the session. This permits a user to complete reads and modifications that were recently permitted but now forbidden. An attacker must tailor an attack to a particular application's pattern of privilege removal and role-specific row security policies. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
