CyberRota Analysis
AI-GeneratedThe FaustWP WordPress plugin prior to version 1.8.11 is vulnerable due to improper authentication of the initialization vector in its token encryption process, allowing a logged-in non-administrator to manipulate the token and gain unauthorized administrator access. This flaw can lead to full control over the WordPress REST API, including the ability to create admin accounts, install plugins, and execute arbitrary code. WordPress site administrators using the affected plugin should prioritize updating to version 1.8.11 to mitigate this high-severity risk.

Original NVD Description
Faust.js is a headless WordPress toolkit. Prior to 1.8.11, the FaustWP WordPress plugin authenticates only the ciphertext in its token envelope and excludes the 16-byte initialization vector from the HMAC in WPE\FaustWP\Auth\encrypt() and WPE\FaustWP\Auth\decrypt() in plugins/faustwp/includes/auth/functions.php. A logged-in non-administrator who obtains an authorization code from GET /generate can modify the unauthenticated initialization vector so that CBC decryption changes the token type and user identifier while the HMAC remains valid. This can produce an access token for an Administrator and permit full WordPress REST API access, administrator-account creation, plugin installation, and arbitrary code execution. This issue is fixed in repository version 1.8.11.
