Improve Seo

Unauthenticated remote code execution in the Improve SEO WordPress plugin (versions through 2.0.11) lets attackers upload executable PHP files by exploiting a file-upload routine that only validates MIME content type while writing files with the attacker-controlled extension into a web-accessible directory. Any visitor can drop a PHP webshell and execute arbitrary code on the server without credentials or user interaction. Publicly available exploit code exists (reported by WPScan), though the EPSS score is low (0.20%, 10th percentile) and it is not on CISA KEV.
