Description OSIDB Bzimport 2026-06-30 16:01:44 UTC 
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. The problem is resolved in PostgreSQL Anonymizer 3.1.2 and later versions
