Quarkus version 3.32.4 is vulnerable to an authorization bypass issue (GHSL-2026-099), in which semicolons (matrix parameters) in HTTP requests can be used to bypass security constraints, potentially allowing unauthorized access to protected resources. Unauthenticated or lower-privileged users can bypass HTTP path-based authorization policies by appending a semicolon (`;`) and arbitrary text to the request URL. The vulnerability arises from a path-normalization inconsistency: Quarkus's security layer performs authorization checks on the raw URL path (which preserves matrix parameters), whereas RESTEasy Reactive's routing layer strips matrix parameters before matching endpoints. This allows requests like `/api/admin;anything` to bypass policies protecting `/api/admin` while still routing to the protected endpoint. Impact This issue may lead to Authentication/Authorization bypasses.
