CVE-2026-22407 is an authorization bypass vulnerability identified in Mikado-Themes Roam, a WordPress theme product, affecting versions up to and including 2.1.1. The vulnerability arises from improper access control mechanisms that rely on user-controlled keys, allowing attackers to bypass authorization checks. Specifically, the theme’s access control security levels are incorrectly configured such that an attacker with limited privileges can manipulate keys or parameters to gain unauthorized access to restricted functionalities or data. The vulnerability is exploitable remotely over the network without user interaction, but it requires the attacker to have some level of authenticated access (PR:L). The CVSS v3.1 base score is 5.4 (medium severity), reflecting low attack complexity and partial impact on confidentiality and integrity, but no impact on availability. No public exploits have been reported yet, indicating the vulnerability is not actively exploited in the wild. The root cause is a design flaw in how the theme handles authorization keys, which should be validated and controlled strictly by the server-side logic rather than relying on user input. This vulnerability could lead to unauthorized data disclosure or modification within affected websites using the Roam theme, potentially compromising site integrity and user data privacy.

For European organizations, this vulnerability poses a moderate risk primarily to websites using the Mikado-Themes Roam WordPress theme. Exploitation could lead to unauthorized access to sensitive information or unauthorized changes to website content, undermining data confidentiality and integrity. This is particularly concerning for businesses relying on their websites for customer interaction, e-commerce, or content management, as unauthorized modifications could damage reputation and trust. While availability is not impacted, the breach of confidentiality and integrity could lead to regulatory compliance issues under GDPR, especially if personal data is exposed or altered. Organizations with limited security monitoring or outdated theme versions are at higher risk. The medium severity score suggests that while the threat is not critical, it should not be ignored, especially in sectors with high data sensitivity such as finance, healthcare, and government services within Europe.

1. Immediately update Mikado-Themes Roam to the latest patched version once available from the vendor. 2. Until patches are released, restrict access to administrative and privileged user accounts to trusted personnel only. 3. Implement strict server-side validation of all authorization keys and parameters to prevent user-controlled manipulation. 4. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests attempting to exploit authorization bypass. 5. Conduct regular audits of user privileges and access logs to identify unusual access patterns or privilege escalations. 6. Educate site administrators on the risks of using outdated themes and the importance of timely updates. 7. Consider isolating critical web applications or deploying additional access controls such as multi-factor authentication to reduce risk. 8. Monitor threat intelligence feeds for any emerging exploit code or attack campaigns targeting this vulnerability.
