CVE-2025-49944 identifies a reflected Cross-site Scripting (XSS) vulnerability in the WPCode Content Ratio plugin for WordPress, developed by Jonatan Jumbert. This vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows an attacker to inject malicious JavaScript code that is reflected back to the user’s browser. The affected versions include all versions up to and including 2.0. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R), such as clicking a malicious link. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability, enabling attackers to steal sensitive information (e.g., cookies, session tokens), manipulate web content, or perform actions on behalf of the user. Although no known exploits are currently active in the wild, the high CVSS score of 7.1 indicates a significant risk. The vulnerability is particularly relevant for WordPress sites using the WPCode Content Ratio plugin, which is used to analyze content ratios on web pages. Since WordPress powers a large proportion of websites globally, including in Europe, this vulnerability poses a notable threat to organizations relying on this plugin for content management and SEO optimization. The lack of available patches at the time of publication necessitates immediate attention to monitoring vendor updates and applying mitigations.

For European organizations, this vulnerability poses a considerable risk to websites using the WPCode Content Ratio plugin. Successful exploitation can lead to theft of user credentials, session hijacking, defacement, or redirection to malicious sites, undermining user trust and potentially causing regulatory compliance issues under GDPR due to data leakage. Public-facing websites, especially those handling sensitive user data or providing critical services, are at heightened risk. The reflected XSS can be leveraged in phishing campaigns targeting employees or customers, increasing the attack surface. Additionally, compromised websites may be blacklisted by search engines, impacting business reputation and revenue. The vulnerability’s ability to affect confidentiality, integrity, and availability means that organizations could face operational disruptions and financial losses. Given the widespread use of WordPress in Europe, the threat is amplified in sectors such as e-commerce, media, and government services that rely heavily on web presence.

1. Monitor the WPCode Content Ratio plugin vendor announcements closely and apply security patches immediately once available. 2. Until patches are released, consider disabling or uninstalling the WPCode Content Ratio plugin if feasible. 3. Deploy and configure Web Application Firewalls (WAFs) with rules specifically designed to detect and block reflected XSS payloads targeting WordPress plugins. 4. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Conduct regular security audits and penetration testing focusing on input validation and output encoding in web applications. 6. Educate users and administrators about the risks of clicking on suspicious links to reduce the chance of successful exploitation requiring user interaction. 7. Use security plugins for WordPress that provide additional XSS protection and input sanitization. 8. Review and harden server and application configurations to minimize exposure of sensitive data in case of compromise.
