Description
WordPress Plugin Modern Events Calendar Lite is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly verify user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Modern Events Calendar Lite version 7.11.0 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 7.12.0 or latest
