xFlow is prone to multiple input-validation vulnerabilities. The issues include cross-site scripting and SQL-injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input. 
 
Successfully exploiting these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, or even exploit vulnerabilities in the underlying database implementation. Other attacks are also possible.
 
xFlow version 5.46.11 is vulnerable to these issues; other versions may also be affected.
