CVE-2026-24945 identifies a missing authorization vulnerability in the Themefic Ultimate Addons for Contact Form 7 WordPress plugin, specifically affecting versions up to 3.5.34. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to bypass authorization checks. This means that certain actions or data that should be restricted to authenticated or privileged users can be accessed or manipulated by attackers without proper permissions. The plugin extends the functionality of Contact Form 7, a widely used WordPress form plugin, by adding additional features and customization options. Due to the missing authorization, attackers could exploit this flaw to perform unauthorized operations such as modifying form settings, accessing sensitive form data, or injecting malicious content. Although no known exploits are currently in the wild, the vulnerability is publicly disclosed and could be targeted by attackers once exploit code becomes available. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity, but the nature of missing authorization typically implies a high risk. The vulnerability affects the confidentiality and integrity of the affected WordPress sites, potentially leading to data breaches or site defacement. Since the plugin is used in WordPress environments, the scope of affected systems includes any websites running the vulnerable plugin version. No authentication or user interaction is required to exploit the missing authorization, increasing the ease of exploitation. The vulnerability was reserved and published in early 2026, with no patch links currently available, indicating that users should monitor vendor updates closely.

For European organizations, the impact of CVE-2026-24945 can be significant, especially for those relying on WordPress websites with the Ultimate Addons for Contact Form 7 plugin installed. Unauthorized access could lead to exposure of sensitive customer data submitted via contact forms, manipulation of form configurations, or injection of malicious content that could compromise website visitors or internal users. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and potential financial losses. Organizations in sectors such as e-commerce, government, healthcare, and education that use WordPress extensively are at higher risk. The vulnerability could also be leveraged as a foothold for further attacks within the network if attackers gain administrative privileges. Given the plugin’s role in enhancing form functionality, exploitation could disrupt business communications and customer interactions. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits rapidly after disclosure. European organizations must consider the risk of targeted attacks exploiting this vulnerability to compromise their web infrastructure and data confidentiality.

To mitigate CVE-2026-24945, organizations should immediately inventory their WordPress installations to identify the presence of the Themefic Ultimate Addons for Contact Form 7 plugin and verify the version in use. Until an official patch is released, restrict access to WordPress administrative interfaces using IP whitelisting, VPNs, or multi-factor authentication to reduce unauthorized access risk. Implement strict role-based access controls within WordPress to limit permissions to only necessary users. Monitor web server and application logs for unusual activities related to form management or unauthorized access attempts. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. Regularly back up website data and configurations to enable quick recovery in case of compromise. Stay informed about vendor updates and apply patches promptly once available. Additionally, conduct security audits and penetration testing focused on WordPress plugins to identify similar misconfigurations proactively. Educate site administrators about the risks of installing unverified plugins and the importance of timely updates.
