CVE-2025-1294 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the eForm - WordPress Form Builder plugin developed by WPQuark. This vulnerability exists in all versions up to and including 4.18.0 due to insufficient sanitization of user input and inadequate output escaping during web page generation. An unauthenticated attacker can exploit this flaw by injecting arbitrary JavaScript code into form-generated pages. Because the malicious script is stored persistently, it executes every time a user accesses the infected page, potentially compromising user sessions, stealing credentials, or performing unauthorized actions on behalf of the user. The vulnerability is remotely exploitable over the network without any privileges or user interaction, increasing its severity and ease of exploitation. The CVSS v3.1 base score is 7.2, reflecting a high severity level with a scope change, as the vulnerability affects not only the plugin but can impact the confidentiality and integrity of user data across the affected WordPress site. 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 by Wordfence and enriched by CISA, indicating recognition by major security entities. Given the popularity of WordPress and the widespread deployment of the eForm plugin, this vulnerability poses a significant risk to websites relying on this form builder for user interactions and data collection.

The impact of CVE-2025-1294 is substantial for organizations using the vulnerable eForm plugin on WordPress sites. Successful exploitation allows attackers to execute arbitrary scripts in the context of the victim's browser, leading to session hijacking, theft of sensitive information such as cookies or credentials, and unauthorized actions performed with the victim's privileges. This can result in data breaches, unauthorized access to user accounts, defacement, or further malware distribution. Since the vulnerability is stored XSS, the malicious payload persists and affects all users visiting the compromised pages, amplifying the attack's reach. The lack of authentication and user interaction requirements lowers the barrier for attackers, increasing the likelihood of exploitation. Organizations hosting customer-facing forms or collecting sensitive data are particularly at risk, as attackers can manipulate form submissions or steal data silently. The vulnerability can also damage organizational reputation and lead to regulatory compliance issues if personal data is compromised. Given the global popularity of WordPress, the scope of affected systems is broad, potentially impacting millions of websites worldwide.

To mitigate CVE-2025-1294, organizations should immediately update the eForm - WordPress Form Builder plugin to a patched version once available. In the absence of an official patch, administrators should implement strict input validation and output encoding on all form inputs and outputs to neutralize malicious scripts. Employing a Web Application Firewall (WAF) with rules targeting XSS payloads can help block exploitation attempts. Restricting permissions on form submission fields and sanitizing stored data in the database can reduce risk. Regularly scanning the website for injected scripts and monitoring logs for suspicious activity is essential. Additionally, applying Content Security Policy (CSP) headers can limit the execution of unauthorized scripts. Educating users and administrators about the risks of XSS and encouraging the use of security plugins that detect and prevent script injections will further enhance defense. Finally, isolating critical administrative interfaces and enforcing multi-factor authentication can mitigate the impact if exploitation occurs.
