CVE-2025-8315: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in emarket-design Simple Contact Form Plugin for WordPress – WP Easy Contact
The WP Easy Contact plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘noaccess_msg’ parameter in all versions up to, and including, 4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-8315 is a stored Cross-Site Scripting (XSS) vulnerability identified in the WP Easy Contact plugin for WordPress, developed by emarket-design. This vulnerability affects all versions up to and including 4.0.1 of the plugin. The root cause is insufficient input sanitization and output escaping of the 'noaccess_msg' parameter, which is used during web page generation. An authenticated attacker with Contributor-level privileges or higher can exploit this flaw by injecting arbitrary malicious scripts into the plugin's stored data. These scripts are then executed in the context of any user who accesses the affected page, potentially leading to session hijacking, privilege escalation, or other malicious activities. The vulnerability has a CVSS v3.1 base score of 6.4, indicating a medium severity level. The attack vector is network-based with low attack complexity, requiring privileges but no user interaction. The scope is changed, meaning the vulnerability can affect resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability falls under CWE-79, which covers improper neutralization of input during web page generation, a common vector for XSS attacks in web applications.
Potential Impact
For European organizations, this vulnerability poses a significant risk, especially those relying on WordPress websites with the WP Easy Contact plugin installed. Exploitation could lead to unauthorized script execution in the browsers of site visitors or administrators, resulting in theft of authentication tokens, defacement, redirection to malicious sites, or installation of malware. This can damage organizational reputation, lead to data breaches, and cause compliance issues under regulations such as GDPR. Since the vulnerability requires Contributor-level access, insider threats or compromised accounts could be leveraged to exploit it. The scope change means that the impact could extend beyond the plugin itself, potentially affecting other parts of the website or connected systems. Given the widespread use of WordPress across Europe, especially among SMEs and public sector entities, the potential for exploitation could be substantial if not mitigated promptly.
Mitigation Recommendations
European organizations should take immediate steps to mitigate this vulnerability. First, they should verify if the WP Easy Contact plugin is installed and identify the version in use. If the plugin is present, restrict Contributor-level access strictly to trusted users and audit existing user privileges to minimize risk. Since no official patch is currently available, organizations should consider temporarily disabling the plugin or removing it if it is not essential. For sites that must continue using the plugin, implementing Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the 'noaccess_msg' parameter can provide interim protection. Additionally, applying Content Security Policy (CSP) headers can help mitigate the impact of injected scripts by restricting script execution sources. Regular monitoring of website logs for unusual activity and user behavior analytics can help detect exploitation attempts early. Finally, organizations should stay alert for vendor updates or patches and apply them promptly once released.
