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 flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries against the backend database without requiring any user interaction or privileges. Given that pmTicket employs a rolling release model for continuous delivery, specific version numbers for affected and patched releases are not clearly defined, complicating patch management. The vendor has not responded to early disclosure attempts, indicating a lack of official remediation or guidance at this time. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, low attack complexity, no privileges or user interaction required, but limited impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. Attackers could leverage this flaw to extract sensitive data, modify or delete records, or escalate further attacks within the affected systems. The absence of vendor patches and the criticality of project management software in organizational workflows heighten the urgency for mitigation.

For European organizations using pmTicket Project-Management-Software, this vulnerability poses a substantial risk to data confidentiality and integrity. Project management platforms often contain sensitive business information, including project plans, personnel data, and strategic documents. Exploitation could lead to unauthorized data disclosure, manipulation of project details, or disruption of project workflows. This could result in operational delays, loss of competitive advantage, and regulatory compliance issues, especially under GDPR mandates concerning data protection. The remote and unauthenticated nature of the exploit increases the attack surface, potentially allowing external threat actors to compromise internal systems without insider access. Additionally, the lack of vendor response and unclear patch availability complicate timely remediation, increasing exposure duration. Organizations relying heavily on pmTicket for critical project coordination may face significant operational and reputational damage if exploited.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the pmTicket application by limiting exposure to trusted internal networks or VPNs, reducing the risk of remote exploitation. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the user_id parameter. Conduct thorough input validation and sanitization at the application layer if source code access is available, implementing parameterized queries or prepared statements to prevent injection. Monitor application logs and database queries for anomalous activity indicative of exploitation attempts. Regularly back up project management data to enable recovery in case of data tampering. Engage in active threat hunting and vulnerability scanning focused on pmTicket instances. Finally, maintain vigilance for vendor updates or community patches and plan for rapid deployment once available.
