CVE-2025-28928 identifies a reflected cross-site scripting (XSS) vulnerability in the 'Are you robot google recaptcha for wordpress' plugin by sureshdsk, affecting versions up to 2.2. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into HTTP responses. When a victim visits a crafted URL containing malicious payloads, the injected script executes in their browser context, potentially compromising session cookies, user credentials, or enabling further attacks such as phishing or malware delivery. This reflected XSS does not require prior authentication, increasing its risk profile, but does require user interaction, typically clicking on a malicious link. The plugin is used to integrate Google reCAPTCHA functionality into WordPress sites, a popular CMS platform, making the attack surface significant. No patches or official fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved and published in March 2025 by Patchstack, but lacks a CVSS score, indicating it is newly disclosed and may require further analysis. The absence of CWE identifiers suggests a straightforward XSS issue without additional complex exploit chains.

The impact of this vulnerability is primarily on the confidentiality and integrity of user sessions and data on affected WordPress sites. Attackers exploiting this reflected XSS can steal session cookies, impersonate users, or perform actions on their behalf, potentially leading to account takeover or unauthorized access. It can also facilitate phishing attacks by injecting deceptive content or redirecting users to malicious websites. For organizations, this can result in reputational damage, data breaches, and compliance violations, especially if sensitive user information is compromised. The availability impact is minimal but could be indirectly affected if attackers use the vulnerability to deploy disruptive scripts. Since the plugin is widely used in WordPress environments globally, the scope of affected systems is considerable. The ease of exploitation without authentication but requiring user interaction makes it a moderate to high risk, especially for public-facing websites with high traffic.

Organizations should immediately verify if their WordPress sites use the 'Are you robot google recaptcha for wordpress' plugin and identify the version in use. If possible, update to a patched version once available from the vendor or plugin repository. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block typical XSS payloads targeting this plugin's parameters. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Sanitize and validate all user inputs rigorously on the server side to prevent injection of malicious code. Educate users and administrators about the risks of clicking untrusted links. Monitor web traffic and logs for suspicious requests that may indicate exploitation attempts. Consider temporarily disabling the plugin if it is not critical to site functionality until a fix is released.
