PostgreSQL JDBC Driver 42.7.13 Released

Mon, 06 Jul 2026 10:18:00 -0400

Adds search_path GUC_REPORT cache invalidation (PG 18+), flushCacheOnDdl, connectExecutor, classLoaderStrategy properties; caps reWriteBatchedInserts to protocol limit; improves batching performance; fixes updatable ResultSet search_path visibility, XA autoCommit, BlobInputStream seek, SSL key-format detection, FIPS trust anchors, and many more.

PostgreSQL JDBC Driver 42.7.12 Released

Mon, 29 Jun 2026 12:00:00 -0400

Security release: fixes silent channel-binding downgrade (CVE-2026-54291). Under channelBinding=require, a server presenting a certificate with an unsupported signature algorithm (e.g. Ed25519) could cause the driver to silently fall back to plain SCRAM-SHA-256, losing man-in-the-middle protection.

PostgreSQL JDBC Driver 42.7.11 Released

Tue, 28 Apr 2026 16:00:00 -0400

Security release: caps SCRAM PBKDF2 iterations (CVE-2026-42198). Adds require_auth, fixes cursor fetching after BEGIN, SSL fallback/timeout handling, COPY hang on IOException, and more.

PostgreSQL JDBC Driver 42.7.7 Released

Wed, 11 Jun 2025 05:00:00 -0400

Notable changes

Security

security: Client Allows Fallback to Insecure Authentication Despite channelBinding=require configuration. Fix channel binding required handling to reject non-SASL authentication Previously, when channel binding was set to “require”, the driver would silently ignore this requirement for non-SASL authentication methods. This could lead to a false sense of security when channel binding was explicitly requested but not actually enforced. The fix ensures that when channel binding is set to “require”, the driver will reject connections that use non-SASL authentication methods or when SASL authentication has not completed properly. See the Security Advisory for more detail. Reported by George MacKerron The following CVE-2025-49146 has been issued
