It is important to fix because\nthis creates a static nonce and since aes-gcm is a stream cipher, this can\nlead to known cryptographic issues, since the same key is being reused.\n(CVE-2021-32791)\n\nIn mod_auth_openidc before version 2.4.9, there is an XSS vulnerability in\nwhen using `OIDCPreservePost On`.
