CVE-2025-7886 is a critical SQL Injection vulnerability identified in the pmTicket Project-Management-Software, specifically affecting the function getUserLanguage within the file classes/class.database.php. The vulnerability arises from improper sanitization or validation of the user_id parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries on the backend database. The product uses a rolling release model, which complicates precise version identification for affected and patched releases. The vendor has not responded to disclosure attempts, and no official patches or updates are currently available. The CVSS 4.0 score is 6.9 (medium severity), reflecting the network attack vector, no required privileges or user interaction, and limited impact on confidentiality, integrity, and availability. However, the vulnerability's ability to be exploited remotely without authentication makes it a significant risk. No known exploits are currently reported in the wild. The lack of vendor response and patch availability increases the urgency for organizations using pmTicket to implement mitigations promptly.

For European organizations utilizing pmTicket Project-Management-Software, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized access to sensitive project management data, including user information, project details, and potentially confidential business information. SQL Injection can also be leveraged to modify or delete data, impacting data integrity and availability of project management services. Given the remote and unauthenticated nature of the exploit, attackers could compromise systems without insider access, increasing the threat surface. This could result in operational disruptions, data breaches, and compliance violations under GDPR if personal data is exposed. The absence of vendor patches means organizations must rely on compensating controls to mitigate risk. The impact is heightened for organizations with critical project management workflows dependent on pmTicket, especially those handling sensitive or regulated data.

1. Immediate mitigation should include implementing Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the user_id parameter in the getUserLanguage function. 2. Conduct thorough input validation and sanitization on all user-supplied inputs at the application layer, particularly user_id, to prevent injection. 3. Employ parameterized queries or prepared statements in the database access code to eliminate direct concatenation of user input into SQL queries. 4. Monitor application logs for suspicious activity indicative of SQL injection attempts. 5. If feasible, isolate the pmTicket application environment to limit database access and reduce potential lateral movement. 6. Engage in active threat hunting to detect any signs of exploitation attempts. 7. Plan for migration to alternative project management solutions if vendor support remains absent. 8. Regularly back up project data to enable recovery in case of data tampering or loss. 9. Stay alert for any future patches or advisories from the vendor or security community.
