The SLES security team deemed this advisory irrelevant for SLES:15.4.
NVD Description
Note: Versions mentioned in the description apply only to the upstream apache2-mod_auth_mellon-doc package and not the apache2-mod_auth_mellon-doc package as distributed by SLES.
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.
