CVE-2026-14672 | BDVDB-2026-358621 Detail
PostgreSQL
Description#
Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count. This requires the probed user to have a non-default scram_iterations count, because the authentication challenge for a nonexistent user reports the default scram_iterations. Within major versions 16-18, minor versions before PostgreSQL 18.6, 17.11, and 16.15 are affected. Versions before PostgreSQL 16 are unaffected.
