Odudeprofile Component is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.

A successful exploit may allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Odudeprofile 2.7 and 2.8 are vulnerable; prior versions may also be affected.
