Red Hat has released a security update for its build of Quarkus 3.27.2 addressing four vulnerabilities: a timing attack in SCRAM authentication, a denial of service due to connection leaks in Hibernate Reactive, HTTP request smuggling via CRLF injection in Netty codec HTTP, and a worker thread exhaustion vulnerability in Quarkus REST. These issues have been rated with moderate severity by Red Hat. The update is intended to fix these vulnerabilities and improve overall stability and security of the product.

This release of Red Hat build of Quarkus 3.20.5 includes the following CVE fixes: * netty-codec-http: Netty (netty-codec-http): Request Smuggling via CRLF Injection [quarkus-3.20] (CVE-2025-67735) * common: Timing Attack Vulnerability in SCRAM Authentication [quarkus-3.20] (CVE-2025-59432) * quarkus-rest: Quarkus REST Worker Thread Exhaustion Vulnerability [quarkus-3.20] (CVE-2025-66560) For more information, see the release notes page listed in the References section.

SCRAM (Salted Challenge Response Authentication Mechanism) is part of the family of Simple Authentication and Security Layer (SASL, RFC 4422) authentication mechanisms. Prior to version 3.2, a timing attack vulnerability exists in the SCRAM Java implementation. The issue arises because Arrays.equals was used to compare secret values such as client proofs and server signatures. Since Arrays.equals performs a short-circuit comparison, the execution time varies depending on how many leading bytes match. This behavior could allow an attacker to perform a timing side-channel attack and potentially infer sensitive authentication material. All users relying on SCRAM authentication are impacted. This vulnerability has been patched in version 3.1 by replacing Arrays.equals with MessageDigest.isEqual, which ensures constant-time comparison.
