e2guardian v5.4.x <= v5.4.3r is affected by missing SSL certificate
validation in the SSL MITM engine. In standalone mode (i.e., acting as a
proxy or a transparent proxy), with SSL MITM enabled, e2guardian, if built
with OpenSSL v1.1.x, did not validate hostnames in certificates of the web
servers that it connected to, and thus was itself vulnerable to MITM
attacks.
