Bumps [org.postgresql:postgresql](https://github.com/pgjdbc/pgjdbc) from 42.7.7 to 42.7.12. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/pgjdbc/pgjdbc/releases";>org.postgresql:postgresql's releases</a>.</em></p> <blockquote> <h2>v42.7.12: security</h2> <h3>Silent channel-binding authentication downgrade (CVE-2026-54291)</h3> <p><code>channelBinding=require</code> 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 guarantee. An attacker who can intercept the TLS connection triggers the downgrade with a certificate whose signature algorithm has no tls-server-end-point channel-binding hash. Examples are Ed25519, Ed448, and post-quantum algorithms.</p> <p>Two issues combine in releases 42.7.4 through 42.7.11:</p> <p>The bundled <code>com.ongres.scram:scram-client</code> (3.1 or 3.2) returns an empty byte array instead of failing when it cannot derive the binding hash for such a certificate. This is the library issue tracked as <a href="https://github.com/ongres/scram/security/advisories/GHSA-p9jg-fcr6-3mhf";>GHSA-p9jg-fcr6-3mhf</a>.</p> <p>pgJDBC does not enforce channelBinding=require where it matters. ScramAuthenticator checks only that the server advertised a -PLUS mechanism; it neither rejects the empty binding nor checks that the negotiated mechanism uses channel binding. The connection therefore downgrades silently.</p> <p>Only connections that set channelBinding=require are affected. Under the default prefer policy, and under allow or disable, falling back to plain SCRAM is the documented behaviour.</p> <p>Releases before 42.7.4 are unaffected, because they do not support channel binding.</p> <h2>v42.7.11</h2> <h2>Security</h2> <ul> <li>fix: Limit SCRAM PBKDF2 iterations accepted from the server. pgjdbc was vulnerable to a client-side denial of service in SCRAM-SHA-256 authentication, where a malicious or compromised PostgreSQL server could specify an extremely large PBKDF2 iteration count, causing the client to consume unbounded CPU and potentially exhaust connection pools. The fix introduces a new scramMaxIterations connection property (defaulting to 100,000) to cap iteration counts before computation begins. See the <a href="https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-98qh-xjc8-98pq";>Security Advisory</a> for more detail.

Under <code>channelBinding=require</code>, the driver silently downgraded from <code>SCRAM-SHA-256-PLUS</code> (with channel binding) to plain <code>SCRAM-SHA-256</code> (without it) when the server presented a certificate whose signature algorithm has no <code>tls-server-end-point</code> channel-binding hash (e.g. Ed25519, Ed448, or post-quantum algorithms). An attacker who can intercept the TLS connection could exploit this to strip channel-binding protection. The fix enforces channel binding in the driver's own code: it now fails the connection when no binding data can be extracted, and verifies the negotiated mechanism uses channel binding (<code>-PLUS</code>) when <code>require</code> is set. Only connections that set <code>channelBinding=require</code> are affected. The default <code>prefer</code> policy and releases before 42.7.4 (which introduced channel-binding support) are unaffected.
