CVE-2022-4102: 
WordPress vulnerability analysis and mitigation

The Royal Elementor Addons WordPress plugin versions before 1.3.56 contained a vulnerability identified as CVE-2022-4102. This security flaw was discovered and publicly disclosed on December 15, 2022, by security researcher Krzysztof Zając. The vulnerability affects the template deletion functionality in the plugin, which lacks proper authorization and CSRF checks (WPScan).

The vulnerability is classified as a Missing Authorization issue (CWE-862) with a CVSS score of 7.1 (High). The technical root cause involves the plugin's failure to implement proper authorization and CSRF checks when deleting templates, combined with insufficient validation to ensure the deleted item is actually a template. This security weakness falls under the OWASP Top 10 category A5: Broken Access Control (WPScan).

When exploited, this vulnerability allows any authenticated user, including those with minimal privileges such as subscribers, to delete arbitrary posts from the WordPress installation. The only requirement is that the attacker knows the slug of the post they want to delete (WPScan).

The vulnerability has been fixed in version 1.3.56 of the Royal Elementor Addons plugin. Users are advised to update to this version or later to protect their WordPress installations (WPScan).
