Description
WordPress Plugin Event Espresso Lite-Event Management and Registration System 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 Event Espresso Lite-Event Management and Registration System version 3.1.37.11.L is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.1.37.12.L or latest
