Description
WordPress Plugin Cryptocurrency Widgets Pack 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 Cryptocurrency Widgets Pack version 1.8.1 is vulnerable; prior versions may also be affected.
Remediation
Disable and remove the plugin until a fix is available
