Description
WordPress Plugin WP Live Chat Support Pro 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 WP Live Chat Support Pro version 8.0.06 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 8.0.07 or latest
