Description
WordPress Plugin Recip.ly 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 Recip.ly versions 1.1.7 and prior are vulnerable.
Remediation
Update to plugin version 1.1.8 or latest
