This vulnerability, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), affects Elated-Themes Mr. SEO plugin versions up to 2.0. It enables unauthenticated attackers to exploit a Local File Inclusion flaw, potentially allowing them to include arbitrary files on the server. The CVSS 3.1 base score is 8.1, indicating high severity with network attack vector, high complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor, and no known exploits are reported in the wild.

Successful exploitation can lead to disclosure of sensitive files, modification of application data, and denial of service, impacting confidentiality, integrity, and availability of the affected system. Because the vulnerability is exploitable without authentication, it poses a significant risk to affected installations.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the vulnerable plugin and consider disabling it if possible. Monitor vendor channels for updates and apply patches promptly once available.
