CVE-2025-10301 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the FunKItools plugin for WordPress, versions up to and including 1.0.2. The root cause is the absence or improper implementation of nonce validation within the saveFields() function, which is responsible for saving plugin settings. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. Without proper nonce checks, an attacker can craft a malicious web page or email containing a request that, when visited or clicked by an authenticated WordPress administrator, causes the plugin to update its settings without the administrator's consent. This attack vector requires no authentication by the attacker but does require that the victim has administrative privileges and interacts with the malicious content (user interaction). The vulnerability affects the integrity of the plugin's configuration but does not directly compromise confidentiality or availability. The CVSS v3.1 base score of 4.3 reflects a network attack vector, low attack complexity, no privileges required, but user interaction is necessary, with an impact limited to integrity. No patches or exploit code are currently publicly available, but the vulnerability is published and should be addressed promptly. The plugin is used within WordPress environments, which are widely deployed across many organizations, including in Europe.

For European organizations, the primary impact of this vulnerability is the potential unauthorized modification of plugin settings within WordPress sites using FunKItools. Such unauthorized changes could lead to misconfigurations that degrade site functionality, weaken security controls, or enable further exploitation by attackers. Although the vulnerability does not directly expose sensitive data or cause denial of service, the integrity compromise can serve as a foothold for more advanced attacks, such as privilege escalation or persistent backdoors if attackers manipulate plugin behavior. Organizations relying on WordPress for critical business functions or customer-facing services could experience reputational damage and operational disruptions if attackers exploit this vulnerability. The requirement for administrator interaction reduces the likelihood of widespread exploitation but does not eliminate risk, especially in environments where administrators may be targeted with phishing or social engineering campaigns. Given the widespread use of WordPress in Europe, particularly in small and medium enterprises and public sector websites, the vulnerability poses a moderate risk that should be mitigated promptly.

To mitigate CVE-2025-10301, organizations should first verify if they use the FunKItools plugin and identify the installed version. Since no official patch is currently available, administrators should consider temporarily disabling the plugin or restricting administrative access to trusted networks to reduce exposure. Implementing strict Content Security Policies (CSP) and SameSite cookie attributes can help reduce CSRF risks by limiting cross-origin requests. Educating administrators about phishing and social engineering risks is critical to prevent inadvertent interaction with malicious links. Monitoring administrative actions and plugin configuration changes can help detect suspicious activity early. Once a patch or update is released by the vendor, organizations must apply it promptly. Additionally, employing Web Application Firewalls (WAFs) with rules to detect and block CSRF attempts targeting the plugin’s endpoints can provide an additional layer of defense. Regular security audits of WordPress plugins and adherence to the principle of least privilege for administrative accounts further reduce risk.
