Published Feb 24, 2023 · Updated Apr 8, 2026

Cross-site request forgery in JoomUnited WP Meta SEO 4.5.3 and earlier allows remote attackers to regenerate sitemaps via a forged request. The regenerateSitemaps function accepts an administrative request without verifying a valid WordPress nonce before rebuilding XML and HTML sitemap output. Exploitation requires an administrator to open an attacker-controlled link, and the reported consequence is limited to unauthorized sitemap regeneration.
