CVE-2026-53712
The CVE describes a vulnerability in the OnGres SCRAM library (com.ongres.scram:scram-client and scram-common) where, prior to version 3.3, a TLS MITM can silently downgrade SCRAM-SHA-256-PLUS with channel binding to SCRAM-SHA-256 without channel binding when an X.509 certificate uses modern sign...
CVE-2026-54291
pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to...
OnGres SCRAM silent channel-binding authentication downgrade via unsupported certificate algorithms
Summary A flaw in com.ongres.scram:scram-client allows an attacker capable of performing a TLS man-in-the-middle MITM attack to silently downgrade a connection from SCRAM-SHA-256-PLUS with channel binding to standard SCRAM-SHA-256 without channel binding, bypassing strict client-side enforcement...
