CVE-2025-67578 identifies a missing authorization vulnerability in the WP Email Capture plugin for WordPress, developed by Rhys Wynne. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing sensitive actions within the plugin. This could allow attackers to bypass authorization checks and potentially access or manipulate email capture data, which is often used for marketing and user engagement purposes. The affected versions include all releases up to and including 3.12.4. Although no public exploits have been reported, the vulnerability's nature suggests that an attacker with network access to the WordPress site could exploit it without requiring user interaction or authentication, depending on the specific access control misconfiguration. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability threatens confidentiality by exposing captured emails, integrity by allowing unauthorized data manipulation, and availability if the plugin's functionality is disrupted. The plugin is widely used in WordPress environments, which are prevalent across European organizations, especially in sectors relying on digital marketing and customer engagement. The vulnerability was published on December 9, 2025, and no patches or exploit mitigations have been linked yet, emphasizing the need for proactive security measures. The vulnerability was assigned by Patchstack, a known authority in WordPress security. Organizations should monitor vendor announcements for patches and audit their plugin configurations to ensure proper access controls are enforced.

The primary impact of CVE-2025-67578 on European organizations lies in the potential unauthorized access to or manipulation of email capture data, which can compromise user privacy and violate data protection regulations such as GDPR. Exposure of captured emails can lead to phishing campaigns, spam, or identity theft targeting European users. Integrity loss could undermine marketing data reliability, affecting business operations and customer trust. Additionally, disruption of plugin functionality could degrade website availability or user experience. Organizations relying on WP Email Capture for lead generation or customer engagement may face operational setbacks and reputational damage. Since WordPress is widely used in Europe, especially among small and medium enterprises, the vulnerability poses a broad risk. Compliance risks are also significant, as unauthorized data exposure could trigger regulatory penalties. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially if attackers develop exploits targeting this vulnerability. The impact is heightened in sectors with stringent data privacy requirements, such as finance, healthcare, and e-commerce, prevalent in countries like Germany and France.

1. Monitor official Rhys Wynne and WP Email Capture plugin channels for security patches addressing CVE-2025-67578 and apply updates immediately upon release. 2. Until patches are available, restrict access to WordPress administrative interfaces and plugin management to trusted personnel only, using strong authentication mechanisms such as multi-factor authentication (MFA). 3. Review and harden access control configurations within the WordPress environment and specifically for the WP Email Capture plugin to ensure that only authorized users can perform sensitive actions. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5. Conduct regular security audits and penetration testing focused on plugin vulnerabilities and access control weaknesses. 6. Limit the exposure of the WordPress site by restricting network access, for example, via IP whitelisting or VPNs for administrative access. 7. Educate site administrators about the risks of unauthorized plugin access and encourage prompt reporting of suspicious activities. 8. Backup email capture data regularly and securely to enable recovery in case of data manipulation or loss. 9. Monitor logs for unusual access patterns or attempts to exploit the plugin. 10. Consider temporary deactivation of the WP Email Capture plugin if the risk is deemed unacceptable and no patch is available.
