CVE-2026-97469 PUBLISHED

PostgreSQL Anonymizer: RESTRICTED functions are reachable through a subLink

Assigner: PostgreSQL
Reserved: 24.09.2026 Published: 25.09.2026 Updated: 25.09.2026

PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to repeatedly call the anon.hash() function and collects (seed, hash_output) pairs to perform an offline brute-force attack and deduce the salt. A masked role can run a RESTRICTED function when the call is placed inside the sub-select. The problem is resolved in PostgreSQL Anonymizer 3.2.3 and later versions
