CVE-2026-24627 identifies a missing authorization vulnerability in the Trusona for WordPress plugin, affecting all versions up to 2.0.0. The vulnerability arises from incorrectly configured access control security levels, which means that certain actions or administrative functions within the plugin can be accessed without proper authorization checks. This flaw can allow an attacker, potentially even unauthenticated, to perform unauthorized operations that should be restricted, such as modifying plugin settings, accessing sensitive authentication data, or manipulating user sessions. Trusona for WordPress is a plugin designed to enhance authentication security, often integrating multi-factor authentication or passwordless login mechanisms. The presence of a missing authorization vulnerability undermines the security guarantees of the plugin and can lead to privilege escalation or unauthorized access within WordPress sites. No CVSS score has been assigned yet, and no patches or known exploits are currently reported. The vulnerability was publicly disclosed on January 23, 2026, by Patchstack. The lack of a patch means that affected organizations must rely on compensating controls and monitoring until an official fix is released. Given WordPress's widespread use in Europe and the adoption of Trusona's authentication solutions, this vulnerability poses a significant risk to the confidentiality and integrity of affected websites.

For European organizations, this vulnerability could lead to unauthorized access to WordPress administrative functions or sensitive authentication data, potentially resulting in site defacement, data leakage, or further compromise of internal networks. Organizations using Trusona for WordPress as part of their authentication infrastructure may see their security posture weakened, increasing the risk of account takeover or privilege escalation attacks. The impact is particularly critical for sectors with high regulatory requirements for data protection, such as finance, healthcare, and government institutions. Additionally, compromised WordPress sites can serve as entry points for broader attacks, including malware distribution or lateral movement within corporate networks. The absence of a patch increases exposure time, and attackers may develop exploits once the vulnerability details become widely known. European organizations with limited security monitoring or delayed patch management processes are especially vulnerable. The reputational damage and potential regulatory penalties from a breach exploiting this vulnerability could be substantial.

Until an official patch is released, European organizations should implement the following specific mitigations: 1) Disable or uninstall the Trusona for WordPress plugin if it is not essential to reduce the attack surface. 2) Restrict access to WordPress administrative interfaces using IP whitelisting or VPN-only access to limit exposure. 3) Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting Trusona plugin endpoints. 4) Conduct thorough audits of user permissions within WordPress to ensure least privilege principles are enforced. 5) Monitor WordPress logs and server logs for unusual activity, such as unauthorized access attempts or changes to plugin configurations. 6) Engage with the vendor or security community to obtain updates on patch availability and apply them promptly once released. 7) Educate site administrators about the risks and encourage immediate reporting of anomalies. 8) Consider deploying additional multi-factor authentication layers independent of the vulnerable plugin to maintain security.
