WordPress Plugin: yet-another-related-posts-plugin: CVE-2022-45374: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

The YARPP plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 5.30.4 via the yarpp shortcode due to insufficient validation on the 'template' user attribute. This allows subscriber-level attackers, and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
