CVE-2026-80099 is an improper-authentication vulnerability in the bundled wp-module-data component used by several Newfold WordPress plugins. The component's authenticate() method runs on the WordPress REST API authentication-error filter. When HiiveConnection::get_auth_token() returns false, PHP type coercion causes the token salt calculation to use an empty string, producing a publicly known SHA-256 value. Because an attacker controls the remaining token inputs—including request method, URL, body, and timestamp—they can generate a valid Bearer token offline. The vulnerable code then authenticates the request as the first WordPress user with the administrator role. Affected releases include Crazy Domains through 2.5.2, Web through 2.3.4, Hostgator through 3.1.0, and Bluehost through 4.17.1; wp-module-data is affected through 2.9.4.

The repository contains a README and one large standalone Python 3 exploit, poc.py. It targets a claimed flaw in Newfold's wp-module-data integration: on sites not connected to Hiive, a false authentication token is reversed and hashed as an empty string, making the Bearer-token salt publicly predictable. The script implements PHP-compatible JSON encoding so it can reproduce the server-side hash over the HTTP method, exact request URL, body, and X-Timestamp header, then submits a forged token to obtain the first WordPress administrator's REST context. It supports single-target checking and threaded mass scanning, optional static Newfold-plugin asset prefiltering, retries, proxy configuration, resumable JSONL output, and vulnerable-host lists. In RCE mode it attempts administrator creation or password takeover followed by ordered theme-editor, ZIP plugin-upload, and inactive-plugin-editor/REST-activation payload delivery. Successful delivery can leave a persistent .fm.php PHP file manager in the target webroot. No hard-coded external command-and-control host, IP address, or fixed victim domain is present; all web requests are constructed from operator-supplied target URLs.

Authentication-bypass vulnerability in wp-module-data through version 2.9.4, bundled in several Newfold WordPress plugins. It enables unauthenticated remote attackers to forge REST API Bearer tokens, assume the first administrator account, and fully take over an affected site, including by creating administrator accounts.
A high-severity, remotely exploitable authentication-bypass vulnerability in the wp-module-data component bundled with several Newfold WordPress plugins. An attacker can forge a Bearer token when the authentication token is absent, impersonate the first WordPress administrator, and take over the affected site through arbitrary REST API actions.
