<h2>Release 1.79.3</h2>
<h1>Security</h1>
<ul>
<li>server: fix an authorization bypass where malformed :path headers
(missing the leading slash) could bypass path-based restricted
&quot;deny&quot; rules in interceptors like <code>grpc/authz</code>. Any
request with a non-canonical path is now immediately rejected with an
<code>Unimplemented</code> error. (<a
