Upgrade org.eclipse.jetty:jetty-util to version 12.0.35, 12.1.9 or higher.
Overview
org.eclipse.jetty:jetty-util is a Web Container & Clients - supports HTTP/2, HTTP/1.1, HTTP/1.0, websocket, servlets, and more.
Affected versions of this package are vulnerable to Use of Non-Canonical URL Paths for Authorization Decisions due to incorrect handling of ; path-parameter segments in the canonicalization loop. An attacker can bypass path-based security checks or reach protected content by sending a request such as /public;/../admin/secret, which leaves the .. segment unnormalized when the path is matched against constraints like SecurityHandler.PathMapped. When the semicolon segment is followed by / and then . or .., the parser carries forward a stale slash state and returns a non-normalized canonical path. That can let requests intended for a protected prefix such as /admin/* be treated as outside the protected path, resulting in unauthorized access to resources that should require authentication.
