0

A vulnerability in PostgreSQL's GSSAPI support allows bypassing pg_hba.conf rules by negotiating GSSAPI authentication improperly. This occurs via an initial direct TLS connection, enabling a connection to proceed with weaker TLS encryption even when GSSAPI is required. The issue affects PostgreSQL major versions 17 and 18, specifically versions before 18.5 and 17.11. Versions prior to 17 are not affected. The vulnerability has a medium severity with a CVSS score of 4.2.

CVE-2026-14681: Improper Enforcement of Message Integrity During Transmission in a Communication Channel in PostgreSQLCVE-2026-14681
0

Improper enforcement of message integrity in PostgreSQL GSSAPI support allows a user to negotiate GSSAPI contrary to pg_hba.conf rules, via initial direct TLS connection. Despite a pg_hba.conf that appears to require GSSAPI, the connection may exchange data over TLS encryption alone. If the TLS settings are more permissive than the GSS settings, the connection may continue with lesser protection. Within major versions 17-18, minor versions before PostgreSQL 18.5 and 17.11 are affected. Versions before PostgreSQL 17 are unaffected.
