CVE-2026-14672 on CTRL-OS 26.05

Aliases: CVE-2026-14672

Packages: postgresql_16, postgresql_17, postgresql_18

Status: Plausible

Advisory Information

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 18.5, 17.11, and 16.15 are affected. Versions before PostgreSQL 16 are unaffected.
