CVE-2026-96255 in Payments for Hubtel Plugin
Summary
by MITRE • 10/01/2026
The Payments for Hubtel WordPress plugin before 1.0.2 does not prevent public access to a debug log in which it records payment requests, including the store's payment gateway API credentials in plain text, allowing unauthenticated attackers to obtain those credentials.

The vulnerability identified in the Payments for Hubtel WordPress plugin prior to version 1.0.2 represents a critical failure in access control and sensitive data handling within the application's debugging infrastructure. The core technical flaw lies in the improper configuration of debug logging mechanisms, which are designed to assist developers in troubleshooting issues during development or testing phases but were inadvertently left accessible in production environments without adequate authentication checks. Specifically, the plugin writes detailed records of payment requests to a log file that is publicly readable via standard HTTP requests. This misconfiguration allows any unauthenticated user on the internet to retrieve this debug log directly through a web browser or automated scraping tools, bypassing all WordPress security layers and administrative privileges typically required for such actions.
The operational impact of this vulnerability is severe due to the nature of the data exposed within these logs. The debug file captures comprehensive details about payment transactions processed by the store, including sensitive customer information and, most critically, the plaintext API credentials used to communicate with external payment gateways. These credentials often include secret keys or tokens that authenticate the plugin's connection to services like Hubtel, Stripe, PayPal, or other financial processors. The exposure of these secrets in plain text means that an attacker can immediately hijack the merchant's ability to process payments, potentially redirecting funds to their own accounts, initiating fraudulent transactions, or using the compromised credentials to access broader administrative interfaces if those systems share authentication mechanisms. This constitutes a direct compromise of confidentiality and integrity for both the business owner and its customers.
From a classification perspective, this vulnerability aligns with CWE-209, which describes the generation of an error message that includes sensitive information, as well as CWE-538, involving file and directory inclusion where insecure defaults lead to exposure of private files. Furthermore, in the context of the MITRE ATT&CK framework for enterprise security, this behavior is indicative of T1213, Data from Information Repositories, where attackers leverage publicly accessible data sources to gather intelligence necessary for further exploitation. The lack of authentication on a file containing secrets also reflects CWE-798, which covers the use of hardcoded credentials or default configurations that facilitate unauthorized access.
Mitigation strategies must focus immediately on restricting access to sensitive files and ensuring secure logging practices. Administrators should upgrade the plugin to version 1.0.2 or later, where this issue has been addressed by implementing proper authentication checks for debug logs or disabling them entirely in production environments. In the interim, manual remediation involves locating the exposed log file via web server configuration or directory listing and either deleting it immediately or moving it outside the public document root so that it cannot be accessed via HTTP requests. Additionally, organizations should rotate all compromised API credentials with their respective payment providers to invalidate any stolen tokens. To prevent future occurrences, developers must adhere to secure coding standards such as OWASP Secure Coding Practices, ensuring that debug information is never written to publicly accessible locations and that sensitive data like API keys are encrypted or stored in environment variables rather than plain text logs.
