PhxContacts is prone to multiple SQL-injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in an SQL query. 
 
A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.
 
PhxContacts 0.93.1 and prior are vulnerable; other versions may also be affected.
