CVE-2025-9952 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the Trinity Audio – Text to Speech AI audio player plugin for WordPress, which converts website content into audio. The vulnerability exists due to improper neutralization of user-supplied input in the 'range-date' parameter, which is insufficiently sanitized and escaped before being included in web page output. This flaw allows unauthenticated attackers to craft malicious URLs containing JavaScript payloads that, when clicked by a victim, execute within the context of the vulnerable website. The attack vector requires no authentication but does require user interaction (clicking a link). The vulnerability impacts confidentiality and integrity by potentially allowing theft of session cookies, user credentials, or manipulation of page content. The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required, but user interaction needed, and a scope change due to potential impact beyond the vulnerable component. No patches were linked at the time of disclosure, and no known exploits are currently active in the wild. The vulnerability affects all plugin versions up to and including 5.20.2, indicating a broad exposure for users who have not updated or mitigated the issue. The CWE classification is CWE-79, which is a common and well-understood web application security weakness.

For European organizations, this vulnerability poses a moderate risk primarily to websites using the Trinity Audio plugin on WordPress. Exploitation can lead to theft of sensitive user data such as session tokens or personal information, unauthorized actions performed on behalf of users, and potential reputational damage if users are exposed to malicious scripts. Public-facing websites that rely on this plugin for accessibility or content delivery are particularly vulnerable. The impact is heightened in sectors with strict data protection regulations like GDPR, where data breaches can result in significant fines and legal consequences. Additionally, compromised user trust and potential service disruption due to injected malicious content can affect business continuity and customer relationships. Although no active exploits are reported, the ease of exploitation and common use of WordPress in Europe make this a relevant threat.

1. Monitor for and apply official patches or updates from the plugin vendor as soon as they become available. 2. In the absence of patches, implement web application firewall (WAF) rules to detect and block malicious payloads targeting the 'range-date' parameter. 3. Employ strict input validation and output encoding on all user-supplied data, especially parameters reflected in web pages. 4. Implement Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce XSS impact. 5. Educate users and administrators about the risks of clicking unsolicited or suspicious links. 6. Regularly audit WordPress plugins and remove or replace those that are outdated or no longer maintained. 7. Use security plugins that can detect and block XSS attempts. 8. Conduct penetration testing and vulnerability scanning focused on web application input handling to identify similar issues proactively.
