WordPress Plugin Infusionsoft Gravity Forms Add-on is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because the application fails to adequately sanitize 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 Infusionsoft Gravity Forms Add-on version 1.5.10 is vulnerable; prior versions may also be affected.
Update to plugin version 1.5.11 or latest
