URLs the same way as most browsers do. As a result, this function can be
bypassed and leads to an Open Redirect vulnerability in the logout
functionality. (CVE-2021-32786)

In mod_auth_openidc before version 2.4.9, the AES GCM encryption in
mod_auth_openidc uses a static IV and AAD. It is important to fix because
this creates a static nonce and since aes-gcm is a stream cipher, this can
lead to known cryptographic issues, since the same key is being reused.
(CVE-2021-32791)

In mod_auth_openidc before version 2.4.9, there is an XSS vulnerability in
when using `OIDCPreservePost On`. (CVE-2021-32792)");
