CVE-2026-82923 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The AI Website Builder WordPress plugin (GitHub build) 1.0.0 does not perform any authorisation or nonce check on its REST API routes, allowing unauthenticated attackers to install and activate plugins and themes, import content from a URL under their control, write a file of their choosing into the uploads directory, and delete site content and media. On a host that serves PHP from the uploads directory, that file write is remote code execution.. EPSS estimates a 0.83% chance of exploitation in the next 30 days.
