CVE-2025-1667 is a critical authorization bypass vulnerability identified in the WPSchoolPress plugin for WordPress, a school management system developed by jdsofttech. The vulnerability stems from the absence of a proper capability check in the wpsp_UpdateTeacher() function, which is responsible for updating teacher user details. This flaw allows any authenticated user with teacher-level privileges or higher to update arbitrary user information, including email addresses of other users. By changing an email address, an attacker can initiate a password reset process, thereby gaining control over accounts with elevated privileges, including administrators. The vulnerability affects all versions of the plugin up to and including 2.2.16. The CVSS 3.1 base score of 8.8 indicates a high-severity issue with network attack vector, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a prime target for attackers aiming to escalate privileges and compromise entire WordPress sites running this plugin. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation. This vulnerability falls under CWE-639, which relates to authorization bypass through user-controlled keys or parameters, highlighting the importance of proper access control checks in web applications handling sensitive user data.

The impact of CVE-2025-1667 is significant for organizations using the WPSchoolPress plugin, particularly educational institutions relying on WordPress for school management. Successful exploitation allows attackers with minimal privileges (teacher-level access) to escalate their privileges to administrator level by modifying user details and resetting passwords. This can lead to full site compromise, data breaches involving sensitive student and staff information, disruption of school operations, and potential reputational damage. The compromise of administrator accounts can also facilitate further attacks such as malware deployment, data exfiltration, or ransomware. Since the vulnerability is remotely exploitable over the network and requires only authenticated access, insider threats or compromised low-privilege accounts can be leveraged to gain full control. The broad impact on confidentiality, integrity, and availability makes this vulnerability critical for any affected organization.

To mitigate CVE-2025-1667, organizations should immediately audit their WordPress installations for the presence of the WPSchoolPress plugin and verify the version in use. If a patched version is released, promptly update to the latest version. In the absence of an official patch, implement the following mitigations: restrict teacher-level user creation and monitor existing teacher accounts for suspicious activity; apply web application firewall (WAF) rules to detect and block unauthorized attempts to invoke the wpsp_UpdateTeacher() function; enforce strong authentication and multi-factor authentication (MFA) for all users with elevated privileges; regularly review and tighten user role permissions to minimize unnecessary access; monitor logs for unusual password reset requests or user detail changes; consider temporarily disabling the plugin if feasible until a fix is available. Additionally, educate staff about phishing and credential security to reduce the risk of initial account compromise.
