      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Mobi-Com Polska Sp. z o.o. stunnel, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9&lt;/p&gt;
&lt;p&gt;A Server-Side Request Forgery (SSRF) bypass vulnerability exists in “stunnel” 5.79 and lower when configured in SOCKS proxy mode. This flaw allows a client to bypass intended localhost restrictions by using IPv4-mapped IPv6 addresses (e.g., “::ffff:127.0.0.1”) or unspecified addresses (&amp;#34;0.0.0.0&amp;#34;, &amp;#34;::&amp;#34;), enabling access to loopback-only services on the &amp;#34;stunnel&amp;#34; host that should not be network-reachable.&lt;/p&gt;</description>
