CVE-2025-26962 identifies a stored cross-site scripting vulnerability in the Easy Contact Form Lite plugin developed by GhozyLab, affecting versions up to and including 1.1.25. The vulnerability stems from improper input sanitization during the generation of web pages, allowing malicious input to be stored and later rendered unsanitized to users. Stored XSS is particularly dangerous because the malicious payload persists on the server and is served to every user who accesses the affected page, increasing the attack surface. Attackers can exploit this vulnerability by submitting crafted input through the contact form, which is then stored and displayed on the website without proper encoding or escaping. This can lead to arbitrary JavaScript execution in victims' browsers, enabling theft of cookies, session tokens, or other sensitive information, as well as potential defacement or redirection attacks. The vulnerability does not require authentication or user interaction beyond visiting the affected page, making it easier to exploit. Although no known exploits have been reported in the wild, the lack of an official patch or update at the time of publication increases risk. The plugin is widely used on WordPress sites, which are popular globally, thus expanding the potential impact. The absence of a CVSS score necessitates an expert severity assessment based on the vulnerability's characteristics and potential consequences.

The impact of CVE-2025-26962 is significant for organizations using the Easy Contact Form Lite plugin on their websites. Successful exploitation can lead to the execution of arbitrary scripts in the context of users' browsers, compromising confidentiality by stealing session cookies or credentials, and integrity by altering displayed content or injecting malicious payloads. Availability impact is generally low but could be indirectly affected if attackers use the vulnerability to deface websites or perform phishing attacks. The stored nature of the XSS means that every visitor to the affected page is at risk, potentially leading to widespread compromise of user accounts or reputational damage. Organizations with high traffic websites or those handling sensitive user data are particularly vulnerable. Additionally, attackers could leverage this vulnerability as a foothold for further attacks, including delivering malware or conducting social engineering campaigns. The absence of known exploits currently provides a window for remediation, but the ease of exploitation and broad exposure make timely mitigation critical.

To mitigate CVE-2025-26962, organizations should immediately assess whether they use the Easy Contact Form Lite plugin version 1.1.25 or earlier. If so, consider temporarily disabling the plugin until an official patch is released. Implement strict input validation and output encoding on all user-supplied data fields, especially those handled by the contact form. Deploy a web application firewall (WAF) with rules specifically targeting XSS payloads to block malicious requests. Monitor web server logs for suspicious input patterns indicative of XSS attempts. Educate site administrators and developers on secure coding practices to prevent similar vulnerabilities. Once a patch becomes available from GhozyLab, apply it promptly and verify the fix through testing. Additionally, consider implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly update all plugins and dependencies to minimize exposure to known vulnerabilities. Finally, conduct periodic security audits and penetration testing to detect and remediate any residual or new vulnerabilities.
