CVE-2025-67628 is a stored Cross-site Scripting (XSS) vulnerability found in the AMP-MODE Review Disclaimer plugin, specifically affecting versions up to 2.0.3. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be embedded persistently within the application. Stored XSS means that the malicious payload is saved on the server and delivered to users when they access the affected pages, increasing the attack surface and potential impact. Attackers can exploit this flaw by injecting JavaScript code into input fields managed by the Review Disclaimer plugin, which is then rendered without proper sanitization. This can lead to session hijacking, theft of cookies, defacement of web content, or redirection to malicious sites. The vulnerability does not require authentication, making it accessible to unauthenticated attackers, and no user interaction beyond visiting the compromised page is necessary to trigger the payload. Although no public exploits have been reported yet, the nature of stored XSS vulnerabilities makes them attractive targets for attackers. The lack of a CVSS score indicates that the vulnerability is newly published and pending further analysis. The plugin is used primarily in WordPress environments where review disclaimers are displayed, often in e-commerce or service review contexts. The absence of patch links suggests that a fix may not yet be available, emphasizing the need for immediate attention from administrators. The vulnerability was reserved and published in December 2025, indicating recent discovery. Overall, this vulnerability represents a significant risk to web applications relying on the AMP-MODE Review Disclaimer plugin due to its potential to compromise user data and site integrity.

For European organizations, the stored XSS vulnerability in the AMP-MODE Review Disclaimer plugin poses several risks. Confidentiality can be compromised through session hijacking and theft of sensitive user information such as cookies or authentication tokens. Integrity of the website content can be undermined by defacement or injection of misleading information, damaging brand reputation and user trust. Availability could be indirectly affected if attackers use the vulnerability to distribute malware or launch phishing campaigns, leading to blacklisting by browsers or search engines. Organizations in sectors like e-commerce, finance, healthcare, and public services, which often rely on user reviews and disclaimers, are particularly vulnerable. The ease of exploitation without authentication increases the likelihood of attacks, potentially leading to widespread compromise if multiple sites use the affected plugin. Additionally, regulatory compliance risks arise under GDPR if personal data is exposed or manipulated. The lack of current known exploits provides a window for proactive mitigation, but the stored nature of the XSS means that once exploited, the impact can be persistent and difficult to remediate quickly.

1. Monitor for official patches or updates from the AMP-MODE vendor and apply them immediately once available. 2. Implement strict input validation and output encoding on all user-supplied data, particularly in the Review Disclaimer plugin inputs. 3. Deploy a robust Content Security Policy (CSP) to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 4. Conduct regular security audits and penetration testing focusing on web application input handling and stored XSS vectors. 5. Use Web Application Firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting the Review Disclaimer plugin. 6. Educate site administrators and developers about secure coding practices and the risks associated with stored XSS. 7. Consider temporarily disabling or replacing the Review Disclaimer plugin if no patch is available and the risk is deemed unacceptable. 8. Monitor web server and application logs for unusual input patterns or script injections related to the plugin. 9. Ensure that user sessions have appropriate security controls such as HttpOnly and Secure flags on cookies to mitigate session theft. 10. Maintain regular backups to enable quick restoration in case of defacement or compromise.
