Doc Text:
A flaw was found in PostgreSQL Anonymizer. An authenticated, unprivileged masked user can bypass access restrictions to execute restricted functions by embedding function calls within a subquery. By repeatedly invoking functions such as anon.hash(), an attacker can collect output to deduce the anonymization salt through offline brute-force attacks, potentially compromising sensitive masked data.

Description OSIDB Bzimport 2026-09-25 15:52:29 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. 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
