Description
WordPress Plugin MM Forms Community is prone to an SQL injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. Successful exploitation requires "magic_quotes" directive set to "Off". WordPress Plugin MM Forms Community version 1.2.3 is vulnerable; other versions may also be affected.
Remediation
Update to plugin version 2.2.6 or latest
