CVE-2023-1023 Information

Description

The WP Meta SEO plugin for WordPress is vulnerable to unauthorized plugin settings update due to a missing capability check on the saveSitemapSettings function in versions up to and including 4.5.3. This makes it possible for authenticated attackers with subscriber-level access to change sitemap-related settings of the plugin. This vulnerability occurred as a result of the plugin relying on nonce checks as a means of access control and that nonce being accessible to all authenticated users regardless of role.
