CVE-2025-1669 identifies a SQL Injection vulnerability in the WPSchoolPress plugin for WordPress, specifically in the 'addNotify' action. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), where user-supplied parameters are not properly escaped or parameterized before being incorporated into SQL queries. This allows an authenticated user with at least teacher-level privileges to append arbitrary SQL commands to existing queries. As a result, attackers can extract sensitive information from the backend database, such as student records or administrative data, without needing higher privileges or user interaction. The vulnerability affects all versions up to and including 2.2.16. The CVSS 3.1 base score is 6.5, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). No public exploits have been reported yet, but the vulnerability is publicly disclosed and should be considered for immediate remediation. The plugin is used in educational environments, making the confidentiality of student and staff data a critical concern.

The primary impact of this vulnerability is unauthorized disclosure of sensitive information stored in the database of affected WordPress sites using the WPSchoolPress plugin. Attackers with teacher-level access can exploit the flaw to extract confidential student data, grades, personal information, and potentially administrative credentials. While the vulnerability does not affect data integrity or availability, the confidentiality breach can lead to privacy violations, regulatory non-compliance (e.g., FERPA, GDPR), reputational damage, and potential legal consequences for educational institutions. Since the attack requires authenticated access, the risk is somewhat mitigated by existing access controls, but insider threats or compromised teacher accounts increase the risk. The vulnerability could also be leveraged as a foothold for further attacks if sensitive credentials or configuration data are exposed. Organizations worldwide using this plugin in their WordPress-based school management systems are at risk, especially those with large user bases and sensitive data.

1. Apply official patches or updates from jdsofttech as soon as they are released to address this vulnerability. 2. Until patches are available, restrict teacher-level and higher privileges to trusted users only and review user access rights regularly. 3. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'addNotify' action. 4. Employ input validation and sanitization on all user-supplied data, especially parameters passed to SQL queries. 5. Encourage the use of prepared statements and parameterized queries in plugin code to prevent SQL injection. 6. Monitor logs for unusual database query patterns or unauthorized data access attempts. 7. Educate staff about phishing and credential security to reduce the risk of account compromise. 8. Consider isolating the WordPress environment and database with strict network segmentation and least privilege principles. 9. Regularly back up data and test restoration procedures to mitigate potential data loss from future attacks.
