CVE-2026-82923: The AI Website Builder WordPress plugin (GitHub build) 1.0.0 does not perform any authorisation or nonce check

This week

CRITICAL 9.8REMOTE

CVE-2026-82923 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

Critical severity
CISA SSVC: public proof of concept
CISA SSVC: automatable with total technical impact
Remotely exploitable, no login, no user action

A fixed release or distro patch exists.
