CVE-2026-50559

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.

Statement

This is an Important flaw in Quarkus where HTTP path-based authorization policies can be bypassed by a remote attacker. Specially crafted HTTP requests containing encoded semicolons, slashes, or backslashes can circumvent security controls, allowing unauthorized access to protected static resources and leading to information disclosure. This is critical in deployments where Quarkus applications serve sensitive static content and rely solely on path-based authorization.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
