CVE-2025-12061 is a vulnerability identified in the TAX SERVICE Electronic HDM WordPress plugin versions before 1.2.1. The core issue stems from missing authorization and Cross-Site Request Forgery (CSRF) checks in an AJAX action endpoint. This flaw allows unauthenticated remote attackers to send specially crafted requests that import and execute arbitrary SQL statements on the backend database. The absence of authorization checks means that no user credentials or privileges are required to exploit this vulnerability, and the lack of CSRF protections further facilitates exploitation by enabling attackers to trick authenticated users into executing malicious requests unknowingly. The vulnerability is classified under CWE-862 (Missing Authorization) and CWE-352 (Cross-Site Request Forgery), indicating both improper access control and insufficient request validation. The CVSS v3.1 base score is 8.6, reflecting a high severity due to the vulnerability's network attack vector, low attack complexity, no privileges required, and no user interaction needed. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component, and the impact is high on confidentiality (C:H) but none on integrity (I:N) or availability (A:N). This means attackers can read sensitive data from the database but cannot modify or delete it or disrupt service availability. The plugin is typically used in electronic tax service environments, which may contain sensitive taxpayer information. Although no known exploits have been reported in the wild yet, the vulnerability's characteristics make it a prime candidate for exploitation once weaponized. The lack of patch links suggests that a fix may be pending or newly released, emphasizing the need for immediate attention from administrators.

For European organizations, especially those involved in tax administration, financial services, or government digital services using the TAX SERVICE Electronic HDM plugin, this vulnerability poses a significant risk. Exploitation can lead to unauthorized disclosure of sensitive taxpayer or financial data, violating data protection regulations such as GDPR. The breach of confidentiality can result in reputational damage, regulatory fines, and loss of public trust. Since the vulnerability allows execution of arbitrary SQL queries, attackers could potentially extract large volumes of sensitive data without detection. Although integrity and availability are not directly impacted, the exposure of confidential data alone is critical. The risk is heightened in countries with advanced e-government services and widespread WordPress adoption. Additionally, the vulnerability could be leveraged as a foothold for further attacks within the network if combined with other vulnerabilities or misconfigurations. The absence of authentication requirements and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation. Organizations failing to patch promptly may face targeted attacks aiming to harvest sensitive fiscal data or disrupt tax-related operations indirectly through data leaks.

Immediate mitigation requires updating the TAX SERVICE Electronic HDM plugin to version 1.2.1 or later where the authorization and CSRF checks are properly implemented. Until an update is applied, organizations should restrict access to the plugin's AJAX endpoints at the web server or application firewall level, allowing only trusted IP addresses or authenticated users to interact with these endpoints. Implementing Web Application Firewalls (WAF) with custom rules to detect and block suspicious SQL injection patterns in AJAX requests can provide temporary protection. Conduct thorough audits of server logs to detect any anomalous or unauthorized AJAX requests indicative of exploitation attempts. Enforce strict role-based access controls within WordPress to minimize exposure. Additionally, organizations should review their database permissions to ensure the WordPress database user has the least privileges necessary, limiting the potential damage from SQL injection. Regular backups of databases and web application files should be maintained to enable recovery in case of compromise. Finally, monitoring threat intelligence feeds for emerging exploit code or attack campaigns targeting this vulnerability will help in proactive defense.
