CVE-2026-14666 on CTRL-OS 26.05

Aliases: CVE-2026-14666

Packages: postgresql_14, postgresql_15, postgresql_16, postgresql_17, postgresql_18

Status: Plausible

Advisory Information

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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
