Bumps org.postgresql:postgresql from 42.7.11 to 42.7.12.

Release notes

Sourced from org.postgresql:postgresql's releases.

v42.7.12: security

Silent channel-binding authentication downgrade (CVE-2026-54291)

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 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.

Two issues combine in releases 42.7.4 through 42.7.11:

The bundled com.ongres.scram:scram-client (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 GHSA-p9jg-fcr6-3mhf.

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.

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.

Releases before 42.7.4 are unaffected, because they do not support channel binding.

[42.7.12] (2026-06-29)

Security

  • fix: Enforce SCRAM channel-binding policy and prevent silent downgrade. Under channelBinding=require, the driver silently downgraded from SCRAM-SHA-256-PLUS (with channel binding) to plain SCRAM-SHA-256 (without it) when the server presented a certificate whose signature algorithm has no tls-server-end-point 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 (-PLUS) when require is set. Only connections that set channelBinding=require are affected. The default prefer policy and releases before 42.7.4 (which introduced channel-binding support) are unaffected. See the Security Advisory for more detail. The following CVE-2026-54291 has been issued.

We'll align with Quarkus version back again instead. See #48990.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
