CVE-2025-14734 in Amazon Affiliate Lite Plugin
Summary
by MITRE • 12/20/2025
The Amazon affiliate lite Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.0. This is due to missing or incorrect nonce validation on the 'ADAL_settings_page' function. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The vulnerability identified as CVE-2025-14734 affects the Amazon affiliate lite Plugin for WordPress, representing a critical security flaw that undermines the integrity of affected systems. This plugin, designed to facilitate amazon affiliate marketing integration within wordpress environments, contains a fundamental security weakness that exposes wordpress sites to potential compromise. The vulnerability manifests specifically within the plugin's administrative interface where proper security controls have been omitted or incorrectly implemented. The flaw exists in the ADAL_settings_page function which fails to validate nonce tokens properly, creating an avenue for malicious actors to manipulate plugin configurations without proper authorization. This represents a classic cross-site request forgery vulnerability that aligns with CWE-352, which defines CSRF as a condition where an application fails to validate that requests originate from legitimate sources. The implications of this vulnerability extend beyond simple configuration changes, as it provides attackers with the capability to alter core plugin settings that may affect site functionality, user data handling, and potentially expose sensitive information.
The technical exploitation of this vulnerability requires minimal prerequisites for attackers, as the flaw does not require authentication to initiate the malicious request. An attacker need only craft a forged request containing the appropriate parameters and convince a logged-in administrator to execute the action, typically through social engineering tactics such as phishing emails or compromised website links. The nonce validation mechanism that should protect against such attacks has been either completely omitted or implemented incorrectly, allowing unauthorized modifications to persist. This vulnerability demonstrates a critical failure in the plugin's security architecture where the absence of proper request validation creates a persistent attack surface. The lack of proper input sanitization and validation in the administrative functions means that any parameter passed to the ADAL_settings_page function can be manipulated by an attacker. This flaw particularly affects the plugin's configuration settings, potentially allowing attackers to modify affiliate tracking parameters, change display settings, or even introduce malicious code through configuration changes that the administrator might not immediately notice.
The operational impact of this vulnerability creates significant risk for wordpress site administrators and their users, as it enables attackers to perform unauthorized modifications to plugin functionality without detection. When an administrator clicks on a malicious link, the forged request executes with the administrator's privileges, potentially leading to complete compromise of the plugin's intended functionality. This could result in altered affiliate tracking codes, modified content display, or even the injection of malicious scripts that persist across multiple user sessions. The vulnerability affects all versions up to and including 1.0.0, meaning that any wordpress installation using this plugin is at risk, regardless of the specific version deployed. The attack vector is particularly dangerous because it leverages the trust relationship between the administrator and the website, making it difficult for users to detect unauthorized modifications. The lack of proper audit logging or immediate notification of configuration changes means that administrators may remain unaware of the compromise until significant damage has occurred.
Organizations and administrators should immediately implement mitigations to protect against exploitation of this vulnerability, beginning with updating to the latest available version of the plugin where the nonce validation has been properly implemented. The recommended approach involves verifying that the plugin has been updated to a version that addresses the specific nonce validation issue, typically through official plugin repositories or direct vendor communication. Additional protective measures include implementing web application firewalls that can detect and block suspicious requests targeting the affected administrative endpoints, and establishing monitoring procedures to detect unusual configuration changes. Administrators should also consider implementing role-based access controls that limit the ability to make configuration changes to only trusted personnel, and conduct regular security audits to identify any unauthorized modifications to plugin settings. The vulnerability highlights the importance of proper security testing and validation, particularly for plugins that handle administrative functions, and emphasizes the need for developers to follow established security frameworks such as those outlined in the OWASP Top Ten project. Organizations should also consider implementing security awareness training for administrators to help them recognize potential social engineering attempts that could exploit this vulnerability.
