ProjeQtor Critical SQL Injection Flaw Exposes Sensitive Data
The National Vulnerability Database has identified CVE-2026-41462, a critical SQL injection vulnerability impacting ProjeQtor versions 7.0 through 12.4.3. This flaw resides in the login functionality, where the username input is directly concatenated into SQL queries without proper sanitization. Attackers can exploit this by injecting malicious SQL code into the username field during authentication.
Successful exploitation allows unauthenticated adversaries to create privileged accounts, exfiltrate sensitive data, and potentially execute operating system commands if the database permissions are elevated. The CVSS score of 9.8 underscores the severity, classifying it as Critical. Defenders must prioritize patching or mitigating this vulnerability to prevent widespread compromise.
What This Means For You
- If your organization uses ProjeQtor, immediately verify your version. If you are running versions 7.0 through 12.4.3, apply vendor patches or implement compensating controls like Web Application Firewalls (WAFs) with specific rules to block SQL injection attempts at the login endpoint. Audit database logs for any unusual account creation or data access patterns.
