CVE-2026-24551 identifies a missing authorization vulnerability in the Monetag Official Plugin (monetagwp) for WordPress, affecting versions up to and including 1.1.3. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker with low privileges (PR:L) to perform unauthorized actions over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality and integrity to a limited extent (C:L/I:L) but does not affect availability (A:N). The plugin likely fails to properly verify whether a user has the necessary permissions before allowing certain operations, which could enable privilege escalation or unauthorized data manipulation within the plugin’s scope. Although no known exploits are currently reported in the wild, the vulnerability presents a risk to WordPress sites using this plugin, especially those that rely on it for monetization or advertising functions. The lack of patches or updates currently listed suggests that users must proactively monitor vendor communications for fixes. The CVSS vector indicates the attack complexity is low (AC:L), meaning exploitation is straightforward once access is obtained. The vulnerability does not require user interaction, increasing its risk profile in automated or scripted attack scenarios.

For European organizations, this vulnerability could lead to unauthorized access or modification of data managed by the Monetag Official Plugin, potentially exposing sensitive monetization or advertising configuration details. While the impact on availability is negligible, the confidentiality and integrity risks could affect business operations relying on accurate and secure plugin functionality. Organizations using this plugin in e-commerce, digital marketing, or content monetization platforms may face risks of data leakage or manipulation, which could result in financial losses or reputational damage. The medium severity rating reflects that while the vulnerability is not critical, it still poses a tangible risk, especially in environments where the plugin is integrated with other critical systems or handles sensitive data. European entities with stringent data protection regulations (e.g., GDPR) must consider the compliance implications of unauthorized data access or modification. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks, especially as exploit code could be developed given the low complexity of the vulnerability.

To mitigate CVE-2026-24551, European organizations should first verify if they are using the Monetag Official Plugin version 1.1.3 or earlier. They should monitor the vendor’s official channels for patches or updates addressing this vulnerability and apply them promptly once available. In the absence of patches, administrators should audit and tighten access control configurations within WordPress and the plugin, ensuring that only trusted users have the necessary privileges to interact with the plugin’s features. Implementing role-based access controls (RBAC) and minimizing the number of users with elevated permissions can reduce exploitation risk. Additionally, organizations should enable detailed logging and monitoring of plugin-related activities to detect any unauthorized access attempts. Network-level protections such as web application firewalls (WAFs) can be configured to restrict access to plugin endpoints or suspicious requests. Regular security assessments and penetration testing focusing on plugin vulnerabilities can help identify and remediate weaknesses before exploitation occurs. Finally, educating site administrators about the risks of installing and maintaining outdated plugins is critical to maintaining a secure environment.
