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
