CVE-2026-82923: CWE-862 Missing Authorization in AI Website Builder (GitHub build)
Description
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.

Technical Analysis
CVE-2026-82923 is a critical vulnerability in the AI Website Builder WordPress plugin (GitHub build) version 1.0.0. The plugin fails to perform any authorization or nonce checks on its REST API endpoints, enabling unauthenticated attackers to execute privileged operations including plugin/theme installation and activation, content importation from arbitrary URLs, arbitrary file writes to the uploads directory, and deletion of site content and media. On hosts configured to execute PHP from the uploads directory, this arbitrary file write can be exploited for remote code execution. The vulnerability is classified under CWE-862 (Missing Authorization).
Potential Impact
Successful exploitation allows unauthenticated attackers to gain full control over the affected WordPress site by installing and activating plugins and themes, importing malicious content, deleting existing content and media, and potentially executing arbitrary code remotely if PHP execution is enabled in the uploads directory. This results in complete compromise of confidentiality, integrity, and availability of the site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the REST API endpoints of the AI Website Builder plugin and disable or remove the plugin if possible to prevent exploitation.
