CVE-2025-14367 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Easy Theme Options plugin for WordPress, developed by corsonr. The vulnerability exists in all versions up to and including 1.0 due to the eto_import_settings function lacking proper authorization checks. This flaw allows any authenticated user with at least Subscriber-level privileges to import arbitrary plugin settings by manipulating the 'eto_import_settings' parameter. Since Subscriber-level access is commonly granted to registered users with minimal privileges, this vulnerability effectively elevates their ability to alter plugin configurations without proper authorization. The attack vector is network-based and does not require user interaction, making it easier to exploit remotely. The vulnerability impacts the integrity of the affected WordPress sites by enabling unauthorized changes to plugin settings, which could be leveraged to weaken security controls or disrupt site functionality. The CVSS 3.1 base score of 5.3 indicates a medium severity level, reflecting the moderate impact on integrity without affecting confidentiality or availability. No patches or official fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved and published in December 2025, with Wordfence as the assigner. Given the widespread use of WordPress and the popularity of plugins for site customization, this vulnerability presents a tangible risk to many websites worldwide.

The primary impact of CVE-2025-14367 is unauthorized modification of plugin settings by low-privileged authenticated users, which compromises the integrity of the affected WordPress sites. Attackers could import malicious or misconfigured settings that may weaken security controls, introduce backdoors, or disrupt normal site operations. While the vulnerability does not directly expose confidential data or cause denial of service, the ability to alter plugin configurations can serve as a stepping stone for further attacks, including privilege escalation or persistent compromise. Organizations relying on the Easy Theme Options plugin risk unauthorized changes that could degrade trustworthiness and operational stability of their websites. Since WordPress powers a significant portion of the web, especially in small to medium enterprises, blogs, and e-commerce, the scope of affected systems is substantial. The ease of exploitation—requiring only authenticated Subscriber-level access—lowers the barrier for attackers, including malicious insiders or compromised user accounts. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks once the vulnerability becomes widely known.

To mitigate CVE-2025-14367, organizations should first verify if they use the Easy Theme Options plugin and identify affected versions (all versions up to 1.0). Since no official patch links are currently available, administrators should consider the following specific actions: 1) Restrict user roles and permissions to minimize Subscriber-level accounts or ensure they are assigned only to trusted users. 2) Implement web application firewall (WAF) rules to detect and block requests containing the 'eto_import_settings' parameter from unauthorized users. 3) Monitor logs for unusual plugin import activity or configuration changes initiated by low-privileged accounts. 4) Temporarily disable or remove the Easy Theme Options plugin if it is not critical to site functionality until a patch is released. 5) Engage with the plugin vendor or WordPress security community for updates or unofficial patches. 6) Harden WordPress installations by enforcing strong authentication, limiting plugin installations to trusted sources, and regularly auditing user privileges. These targeted mitigations go beyond generic advice by focusing on controlling access to the vulnerable functionality and monitoring for exploitation attempts.
