EventON - WordPress Virtual Event Calendar Plugin <= 5.0.11 - Unauthenticated Blind SQL Injection via Search Parameter

EventON (Pro) - WordPress Virtual Event Calendar Plugin: Currently marked unpatched

Affected versions: *-5.0.11

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The EventON - WordPress Virtual Event Calendar Plugin plugin for WordPress (full) is vulnerable to SQL Injection via the WordPress 'search' parameter in versions up to, and including, 5.0.11 due to insufficient escaping on the user supplied parameter and lack of preparation on the existing SQL query.
