Description
WordPress Plugin Secure Copy Content Protection and Content Locking 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. WordPress Plugin Secure Copy Content Protection and Content Locking version 2.6.6 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.6.7 or latest
