CVE-2024-49319 is a cross-site scripting (XSS) vulnerability identified in the Awesome Contact Form7 for Elementor plugin developed by B.M. Rafiul Alam. The vulnerability exists due to improper neutralization of input during the generation of web pages, which allows an attacker to inject malicious scripts into the content rendered by the plugin. This plugin integrates with Elementor, a popular WordPress page builder, to provide enhanced contact form functionality. Versions up to and including 3.0 are affected. The vulnerability can be exploited by an attacker who crafts malicious input that is not properly sanitized or escaped before being included in the web page output. When a victim views the affected page, the injected script executes in their browser context, potentially leading to session hijacking, theft of cookies, defacement, or redirecting users to malicious websites. No authentication is required to exploit this vulnerability, and user interaction (such as visiting a maliciously crafted page) is necessary to trigger the attack. As of the publication date, no official patches or updates have been released, and no known exploits have been observed in the wild. The vulnerability was reserved and published in October 2024, with Patchstack as the assigner. The lack of a CVSS score necessitates an independent severity assessment. Given the widespread use of WordPress and Elementor, and the common deployment of contact form plugins, this vulnerability represents a significant risk to website integrity and user security.

The impact of CVE-2024-49319 is primarily on the confidentiality and integrity of affected websites and their users. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of the victim’s browser, enabling attackers to steal session cookies, perform actions on behalf of users, or redirect users to malicious sites. This can result in account compromise, data theft, phishing, and reputational damage to organizations. For e-commerce, financial, or sensitive data-handling websites, the consequences can be severe, including loss of customer trust and potential regulatory penalties. The availability impact is generally low, as XSS does not directly disrupt service but can be leveraged as a stepping stone for further attacks. Since the vulnerability does not require authentication, any visitor to the affected page can be targeted, increasing the attack surface. Organizations worldwide using this plugin in their WordPress environments are at risk, especially those with high traffic or sensitive user data. The absence of known exploits in the wild provides a window for proactive mitigation before widespread exploitation occurs.

To mitigate CVE-2024-49319, organizations should first monitor for updates or patches released by the plugin developer or trusted security sources and apply them promptly once available. In the absence of an official patch, administrators should consider temporarily disabling or removing the Awesome Contact Form7 for Elementor plugin to eliminate exposure. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads can provide interim protection. Website owners should also audit their input validation and output encoding practices, ensuring that all user-supplied data is properly sanitized and escaped before rendering. Employing Content Security Policy (CSP) headers can reduce the impact of XSS by restricting script execution sources. Regular security scanning and penetration testing should be conducted to detect any residual vulnerabilities. Additionally, educating users about phishing and suspicious links can reduce the effectiveness of social engineering attacks leveraging this vulnerability. Finally, consider alternative contact form plugins with a strong security track record if immediate patching is not feasible.
