CVE-2024-56011 identifies a stored cross-site scripting (XSS) vulnerability in the Responsive Google Maps plugin developed by Ilja Zaglov, specifically affecting versions up to and including 1.2.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be stored persistently within the plugin's data handling processes. When a victim accesses a compromised page, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. Stored XSS is particularly dangerous because the malicious payload remains on the server and affects all users who visit the infected page. This vulnerability does not require user authentication, increasing its risk profile. Although no public exploits have been reported yet, the widespread use of WordPress and its plugins makes this a critical concern. The lack of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed, but the nature of stored XSS vulnerabilities typically warrants high severity. The plugin is commonly used to embed Google Maps responsively on websites, meaning many small to medium businesses and organizations could be affected. The absence of an official patch at the time of disclosure necessitates immediate attention to mitigation strategies.

The impact of CVE-2024-56011 can be severe for organizations using the Responsive Google Maps plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the affected website, compromising user confidentiality and integrity. This can lead to theft of sensitive information such as login credentials, personal data, and session tokens. Attackers may also perform actions on behalf of users, including changing account settings or conducting fraudulent transactions. The persistent nature of stored XSS means that all visitors to the infected page are at risk, potentially damaging the organization's reputation and trustworthiness. For e-commerce, financial services, and any site handling sensitive user data, the consequences can include regulatory penalties and loss of customer confidence. Additionally, attackers might use the vulnerability as a foothold for further attacks, including malware distribution or pivoting to internal networks. Given the plugin’s popularity among WordPress users worldwide, the scope of affected systems is broad, increasing the potential global impact.

To mitigate CVE-2024-56011, organizations should immediately audit their use of the Responsive Google Maps plugin and restrict or disable it if possible until a patch is released. Implement strict input validation and sanitization on all user inputs that interact with the plugin, ensuring that any data stored or rendered is properly escaped and encoded to prevent script execution. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. Monitor web application logs for unusual input patterns or script injections. Educate developers and administrators about secure coding practices related to output encoding and input handling. If feasible, replace the vulnerable plugin with alternative, well-maintained mapping solutions that follow secure development standards. Stay alert for official patches or updates from the vendor and apply them promptly. Additionally, conduct regular security assessments and penetration testing focusing on XSS vulnerabilities to detect similar issues proactively.
