Description
WordPress Plugin Quick Page/Post Redirect is prone to an open redirect vulnerability because the application fails to properly verify user-supplied input. Exploiting this issue may allow attackers to redirect users to arbitrary web sites and conduct phishing attacks; other attacks are also possible. WordPress Plugin Quick Page/Post Redirect version 5.1.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 5.1.6 or latest
