The WP Codeus Advanced Sermons plugin contains a reflected XSS vulnerability (CWE-79) due to improper input sanitization during web page generation. This vulnerability affects all versions up to 3.1 and allows attackers to inject malicious scripts that execute when a user interacts with crafted content. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability. No patch or official remediation level has been disclosed by the vendor or in the advisory data.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to information disclosure, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of the affected system. Since the vulnerability is reflected XSS, it requires user interaction to trigger. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying temporary mitigations such as disabling or restricting the use of the affected plugin or employing web application firewalls (WAF) with XSS filtering capabilities. Monitor vendor channels for updates and apply patches promptly once available.
