2 vulnerabilities found for Red Hat build of Quarkus 3.20.6.SP2 by Red Hat

CVE-2026-50559 (GCVE-0-2026-50559)

Vulnerability from nvd – Published: 2026-06-19 20:26 – Updated: 2026-08-13 12:04

Title

Authentication/Authorization Bypass via Advanced Path Normalization Vulnerabilities

Summary

Quarkus is a Java framework for building cloud-native applications. Prior to versions 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2, Quarkus HTTP path-based authorization policies can be bypassed using encoded semicolons (%3B) to smuggle matrix parameters past the security layer, and using encoded slashes (%2F) or backslashes (%5C) to access protected static resources. This is a distinct issue from CVE-2026-39852, which addressed only literal semicolon stripping. Versions 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2 contain a patch.
