Name of the Vulnerable Software and Affected Versions WP Meta SEO plugin for WordPress versions up to, and including, 4.5.3

Description The issue arises from a missing capability check on the regenerateSitemaps function, allowing authenticated attackers with subscriber-level access to generate sitemaps. This is due to the plugin relying on nonce checks for access control, which are accessible to all authenticated users regardless of role.

Recommendations For versions up to, and including, 4.5.3, consider updating to a version that includes a fix for this issue, as the current version allows unauthorized sitemap generation due to the missing capability check on the regenerateSitemaps function. As a temporary workaround, consider restricting access to the regenerateSitemaps function to prevent unauthorized sitemap generation.
