Loading vulnerability…
DIGITS: WordPress Mobile Number Signup and Login versions before 8.4.6.1 fail to rate-limit one-time-password (OTP) validation attempts. An attacker can repeatedly submit OTP guesses, making brute-force of OTP validation straightforward.

This repository contains a Python exploit script targeting CVE-2025-4094, a vulnerability in the WordPress Digits plugin (versions prior to 8.4.6.1) that allows OTP authentication bypass via brute-force. The main script, 'digits_otp_bypass_cve2025-4094.py', takes as input the target URL (typically the '/wp-admin/admin-ajax.php' endpoint), a phone number, and an instance ID (which must be obtained from an intercepted legitimate request). The script uses a ThreadPoolExecutor to parallelize brute-force attempts of OTP values (4 or 6 digits), sending POST requests to the target endpoint with the required parameters. If a valid OTP is found, it is displayed along with a snippet of the server's response. The repository also includes a README with detailed usage instructions and a requirements.txt listing dependencies. The exploit is operational, requiring some knowledge of the target (phone number and instance ID), and is intended for use in authorized security testing scenarios.
This repository provides a proof-of-concept exploit for CVE-2025-4094, a critical authentication bypass vulnerability in the WordPress Digits plugin prior to version 8.4.6.1. The vulnerability arises from a lack of rate limiting on the OTP verification endpoint, allowing attackers to brute-force OTP codes and bypass SMS-based authentication or reset passwords. The repository contains two files: a detailed README.md explaining the vulnerability, exploitation steps, and references, and a Python script (digits_otp_bypass_cve2025-4094.py) that automates the brute-force attack. The script requires the attacker to supply real request parameters (such as phone number, instance ID, form ID, and referer) captured from a legitimate OTP request. It then iterates through all possible OTP values (default 4-digit, configurable to 6-digit) and sends POST requests to the target's /wp-admin/admin-ajax.php endpoint, checking for a successful authentication response. The exploit is a functional proof-of-concept and does not include weaponized features or payload customization. No hardcoded real-world endpoints are present; placeholders are used, and the attacker must supply target-specific values.
