Rank Math SEO plugin versions up to 1.0.119 are vulnerable to stored cross-site scripting (XSS) attacks due to insufficient input sanitization and output escaping for user-specified attributes.
This security monitor allows an authenticated attacker with poster-level access or higher to inject arbitrary web script into the page.
These malicious scripts can run every time a user visits the injected page, putting the integrity of your website and the safety of your visitors at risk.
Stored XSS attacks are particularly insidious because the injected script is permanently stored on the target server. Therefore, even if an attacker does not redistribute malicious code, it can potentially impact multiple users over time.
