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.

Description A flaw was found in Quarkus. A remote attacker could bypass HTTP path-based authorization policies by using specially crafted encoded semicolons, slashes, or backslashes in HTTP requests. This could allow unauthorized access to protected static resources, leading to information disclosure. Quarkus is a Java framework for building cloud-native applications.
