CVE-2025-14855 is a stored cross-site scripting (XSS) vulnerability identified in the SureForms plugin for WordPress, which is widely used for creating contact, payment, and custom forms. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), specifically due to insufficient sanitization and escaping of form field parameters. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into form fields that are stored and later rendered on web pages. When any user accesses the affected page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability affects all versions up to and including 2.2.0 of the SureForms plugin. The CVSS v3.1 score is 7.2, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and a scope change (S:C) that affects components beyond the vulnerable plugin. The impact primarily affects confidentiality and integrity, with no direct availability impact. Although no public exploits have been reported yet, the vulnerability’s characteristics make it a prime target for attackers, especially given the plugin’s use in handling sensitive payment and contact information. The lack of a current patch or mitigation increases the urgency for affected organizations to implement compensating controls. This vulnerability is particularly concerning because it can be exploited remotely without authentication or user interaction, increasing the risk of widespread exploitation on vulnerable WordPress sites.

For European organizations, the impact of CVE-2025-14855 can be significant, especially for those relying on the SureForms plugin for customer interaction, payment processing, or data collection. Exploitation could lead to theft of sensitive customer data, including personal and payment information, undermining confidentiality. Attackers could also manipulate form data or inject phishing content, damaging the integrity of the website and eroding customer trust. Since the vulnerability allows script execution in users’ browsers, it can facilitate session hijacking and unauthorized actions, potentially leading to account compromise or fraudulent transactions. The reputational damage and regulatory consequences under GDPR for data breaches could be severe. Additionally, the vulnerability’s exploitation could serve as a foothold for further attacks within the network. Given the plugin’s widespread use in e-commerce and service websites, the threat extends to critical sectors such as finance, retail, and public services across Europe.

1. Immediate action should be taken to monitor for updates from Brainstormforce and apply patches as soon as they are released. 2. Until a patch is available, consider disabling the SureForms plugin or replacing it with alternative, secure form plugins. 3. Deploy a Web Application Firewall (WAF) with rules specifically targeting XSS payloads and suspicious form submissions to block exploitation attempts. 4. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Conduct thorough input validation and output encoding on all form inputs, especially if custom code interacts with SureForms data. 6. Regularly audit and sanitize stored form data to detect and remove any injected scripts. 7. Educate website administrators and developers about the risks of stored XSS and secure coding practices. 8. Monitor web server and application logs for unusual activity indicative of exploitation attempts. 9. Use security plugins that can detect and alert on suspicious code injections within WordPress environments. 10. Prepare incident response plans to quickly address any successful exploitation and data breaches.
