GHSA-rc95-pcm8-65v9

Quarkus has Authentication/Authorization bypasses

Quick fix

GHSA-rc95-pcm8-65v9 — io.quarkus:quarkus-vertx-http: upgrade to the fixed version with the command below.

# pom.xml: bump <version>3.20.6.1</version> for io.quarkus:quarkus-vertx-http

Details

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](https://quarkus.io/guides/security-authorize-web-endpoints-reference) 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.

### Credits

This issue was discovered with the [GitHub Security Lab Taskflow Agent](https://github.com/GitHubSecurityLab/seclab-taskflow-agent) and manually verified by GHSL team members [@p- (Peter Stöckli)](https://github.com/p-) and [@m-y-mo (Man Yue Mo)](https://github.com/m-y-mo).
