CVE-2025-69102 is a reflected Cross-site Scripting (XSS) vulnerability identified in the WP Test Email plugin for WordPress, developed by Boopathi Rajan. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages dynamically generated by the plugin. When a victim interacts with a crafted URL or input, the malicious script executes in their browser context, potentially enabling theft of session cookies, redirection to malicious sites, or unauthorized actions on behalf of the user. The vulnerability affects all versions of WP Test Email up to and including 1.1.7. The CVSS v3.1 base score is 7.1, indicating high severity, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction is necessary. The scope is changed, meaning the vulnerability can affect resources beyond the vulnerable component. The impact includes low confidentiality, integrity, and availability losses, consistent with typical reflected XSS attacks. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is used to test email functionality in WordPress environments, which are widely deployed globally, including Europe. The vulnerability could be exploited by attackers to target site administrators or users, potentially leading to session hijacking, phishing, or further exploitation of the site.

For European organizations, this vulnerability poses a significant risk primarily to websites running WordPress with the WP Test Email plugin installed. Exploitation could lead to unauthorized disclosure of sensitive information such as session tokens or user credentials, enabling attackers to impersonate users or administrators. This could further facilitate privilege escalation or persistent access. The reflected XSS nature means attacks require user interaction, often through social engineering, but the widespread use of WordPress in Europe increases the attack surface. Compromise of email testing functionality could disrupt operational workflows or be leveraged as a stepping stone for broader attacks. Additionally, regulatory frameworks like GDPR impose strict data protection requirements; exploitation leading to data breaches could result in legal and financial penalties. The lack of available patches increases the urgency for mitigation. Organizations with public-facing WordPress sites, especially those in sectors such as finance, healthcare, and government, are at heightened risk due to the potential impact on confidentiality and trust.

1. Immediately audit all WordPress installations for the presence of the WP Test Email plugin and identify versions up to 1.1.7. 2. Disable or uninstall the WP Test Email plugin until a security patch is released. 3. If the plugin is essential, implement strict input validation and output encoding on all user-supplied data within the plugin’s code to neutralize malicious scripts. 4. Employ Web Application Firewalls (WAFs) with rules to detect and block reflected XSS attack patterns targeting the plugin’s endpoints. 5. Educate users and administrators about the risks of clicking untrusted links that could exploit reflected XSS. 6. Monitor web server and application logs for unusual requests or error patterns indicative of attempted exploitation. 7. Keep WordPress core and all plugins updated regularly and subscribe to security advisories from the plugin vendor and trusted sources. 8. Implement Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 9. Prepare incident response plans to quickly address any detected exploitation attempts. 10. Coordinate with hosting providers to apply network-level protections and rapid patch deployment once available.
