CVE-2026-24522 identifies a Missing Authorization vulnerability in the MyThemeShop WP Subscribe plugin for WordPress, affecting versions up to 1.2.16. This vulnerability arises from incorrectly configured access control mechanisms within the plugin, allowing users with low privileges (PR:L) to perform actions or access data that should be restricted. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), which increases the risk of automated exploitation. However, the impact is limited to confidentiality (C:L), with no direct effect on integrity or availability. The vulnerability does not require elevated privileges beyond low-level authenticated access, indicating that an attacker must have some form of login credentials but not administrative rights. The plugin is commonly used to manage subscription forms and related user data on WordPress sites, so unauthorized access could expose subscriber information or allow manipulation of subscription settings. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and assigned a CVSS score of 4.3, categorized as medium severity. The issue highlights the importance of proper authorization checks in WordPress plugins, especially those handling user data. Organizations relying on this plugin should be aware of the risk and prepare to apply updates or mitigations once released.

For European organizations, the primary impact of CVE-2026-24522 is the potential unauthorized disclosure of subscriber information managed through the WP Subscribe plugin. This could lead to privacy violations under GDPR if personal data is exposed, resulting in regulatory penalties and reputational damage. Although the vulnerability does not allow modification or deletion of data, unauthorized access to subscription data can facilitate targeted phishing or social engineering attacks. The lack of required user interaction and the network-based attack vector mean that attackers can attempt exploitation remotely, increasing the risk for publicly accessible WordPress sites. Organizations with customer-facing subscription forms or newsletters are particularly at risk. The medium severity reflects a moderate risk profile, but the impact on confidentiality combined with regulatory compliance concerns makes timely mitigation important. Additionally, the exposure of subscription data could indirectly affect business operations by undermining customer trust.

1. Monitor MyThemeShop announcements and security advisories for an official patch addressing CVE-2026-24522 and apply updates immediately upon release. 2. Until patched, restrict access to the WP Subscribe plugin’s administrative and subscription management interfaces using WordPress role-based permissions, ensuring only trusted users have low-level access. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting WP Subscribe endpoints. 4. Conduct regular audits of user accounts with low privileges to ensure no unauthorized users have access. 5. Employ network segmentation and IP whitelisting where possible to limit access to WordPress admin areas. 6. Review and tighten WordPress security configurations, including disabling unnecessary plugins and enforcing strong authentication mechanisms. 7. Monitor logs for unusual access patterns related to subscription management functions. 8. Consider temporarily disabling the WP Subscribe plugin if it is not critical to operations until a patch is available.
