Description
WordPress Plugin Simple Events Calendar 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 Simple Events Calendar version 1.4.0 is vulnerable; prior versions may also be affected.
Remediation
Edit the source code to ensure that input is properly sanitised or disable the plugin until a fix is available
