Description
WordPress Plugin Modern Events Calendar Lite is prone to multiple vulnerabilities, including arbitrary file upload and SQL injection vulnerabilities because it fails to properly sanitize and verify user-supplied input. An attacker may leverage these issues to upload arbitrary code and run it in the context of the webserver process, which may facilitate unauthorized access or privilege escalation, or to compromise the application, access or modify data or to exploit vulnerabilities in the underlying database. WordPress Plugin Modern Events Calendar Lite version 5.16.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 5.16.6 or latest
