CVE-2025-14875 in Payment Gateway for WooCommerce Plugin
Summary
by MITRE • 01/07/2026
The HBLPAY Payment Gateway for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘cusdata’ parameter in all versions up to, and including, 5.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The CVE-2025-14875 vulnerability affects the HBLPAY Payment Gateway for WooCommerce plugin, a widely used payment processing solution within the WordPress ecosystem. This particular flaw exists in versions up to and including 5.0.0, representing a significant security risk for e-commerce websites that rely on this plugin for transaction processing. The vulnerability stems from inadequate input validation and output escaping mechanisms within the plugin's codebase, creating an exploitable entry point for malicious actors targeting WordPress installations. The specific parameter 'cusdata' serves as the attack vector, making it possible for unauthenticated threat actors to inject malicious scripts that could compromise user sessions and data integrity.
The technical implementation of this reflected cross-site scripting vulnerability occurs when user input from the 'cusdata' parameter is not properly sanitized before being rendered in web pages. This failure to adequately escape output creates an environment where attacker-controlled data can be executed as script code within the browser context of legitimate users. The vulnerability classification aligns with CWE-79, which specifically addresses Cross-Site Scripting flaws, and represents a direct violation of secure coding practices that mandate proper input validation and output encoding. Attackers can craft malicious URLs containing script payloads that, when clicked by unsuspecting users, execute in their browsers and potentially steal session cookies, redirect to malicious sites, or perform other harmful actions.
The operational impact of this vulnerability extends beyond simple script injection, as it can lead to complete session hijacking and unauthorized access to customer payment information. Unauthenticated attackers can exploit this weakness to execute arbitrary code in the context of a victim's browser, potentially leading to account takeovers, data exfiltration, and financial fraud. The reflected nature of the vulnerability means that the malicious script is reflected back to the user through the web application's response, making it particularly dangerous as it can be delivered through various attack vectors including email phishing campaigns, compromised websites, or social engineering tactics. This vulnerability directly impacts the integrity and confidentiality of payment processing operations, potentially exposing sensitive customer data and undermining trust in the affected e-commerce platforms.
Mitigation strategies for CVE-2025-14875 should prioritize immediate plugin updates to versions that address the reflected XSS vulnerability through proper input sanitization and output escaping mechanisms. Organizations should implement web application firewalls that can detect and block malicious script payloads targeting the 'cusdata' parameter, while also applying input validation filters that prevent script injection attempts. Security monitoring should include regular scanning for vulnerable plugin versions and implementation of content security policies that restrict script execution within the affected web applications. The vulnerability also highlights the importance of following ATT&CK framework principles for defensive measures, particularly those related to input validation and output encoding as defensive techniques against web-based attacks. Regular security audits and vulnerability assessments should be conducted to identify similar issues in other plugins and themes, ensuring comprehensive protection against similar reflected XSS vulnerabilities throughout the WordPress environment.
