CVE-2026-87743 PUBLISHED

Quarkus-vertx-http: authorization bypass via path normalization discrepancy in quarkus http security

Assigner: redhat
Reserved: 09.09.2026 Published: 18.09.2026 Updated: 18.09.2026

A flaw was found in Quarkus HTTP security. An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information.
