CVE-2025-14734 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Amazon affiliate lite Plugin for WordPress, specifically in all versions up to and including 1.0.0. The vulnerability stems from the absence or improper implementation of nonce validation in the 'ADAL_settings_page' function, which handles plugin settings. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. Without proper nonce checks, attackers can craft malicious web requests that, when executed by an authenticated administrator (via clicking a link or visiting a crafted webpage), cause unauthorized changes to plugin settings. This attack vector requires no prior authentication by the attacker but does require user interaction from an administrator, making it a classic CSRF scenario. The vulnerability impacts the integrity of the plugin's configuration and can potentially affect site availability if settings are altered maliciously. The CVSS v3.1 score of 5.4 reflects a medium severity, considering the attack vector is network-based, requires no privileges, but does require user interaction. No patches or exploit code are currently publicly available, and no known exploits have been observed in the wild. The vulnerability is cataloged under CWE-352, which covers CSRF issues. Given the widespread use of WordPress and the popularity of affiliate marketing plugins, this vulnerability could be leveraged to disrupt affiliate configurations or redirect affiliate revenue streams.

For European organizations, the impact of this vulnerability primarily concerns the integrity and availability of WordPress sites using the Amazon affiliate lite Plugin. Unauthorized changes to plugin settings could disrupt affiliate marketing operations, leading to financial losses or reputational damage. If attackers manipulate affiliate links or disable plugin functionality, organizations relying on affiliate revenue could see reduced income. Additionally, altered settings might introduce further security risks or site instability, affecting availability. Since the attack requires an administrator to be tricked into clicking a malicious link, organizations with less awareness of phishing risks are more vulnerable. The confidentiality of data is not directly impacted by this vulnerability. However, compromised site integrity could indirectly lead to broader security issues if attackers leverage altered settings to introduce malicious content or redirect users. The medium severity rating suggests a moderate risk level, but the potential for targeted attacks against high-value affiliate sites in Europe is notable.

To mitigate this vulnerability, organizations should first verify if they are using the Amazon affiliate lite Plugin for WordPress, particularly versions up to 1.0.0. Since no official patch is currently available, administrators should implement manual nonce validation in the 'ADAL_settings_page' function to ensure requests are legitimate. Restrict administrative access to trusted personnel and enforce multi-factor authentication (MFA) to reduce the risk of compromised credentials. Educate site administrators about phishing and social engineering tactics to minimize the likelihood of clicking malicious links. Employ web application firewalls (WAFs) that can detect and block CSRF attack patterns. Regularly monitor plugin settings and site logs for unauthorized changes. Consider temporarily disabling the plugin if it is not critical or replacing it with a more secure alternative until an official patch is released. Maintain up-to-date backups to enable rapid recovery in case of compromise.
