- A flaw was found in mod_auth_mellon where it does not sanitize logout URLs properly. This issue could be
used by an attacker to facilitate phishing attacks by tricking users into visiting a trusted web
application URL that redirects to an external and potentially malicious server. The highest threat from
this liability is to confidentiality and integrity. (CVE-2021-3639)
