6.1
CVSS v3.1
Official Description
In WordPress before 4.7.3 (wp-includes/pluggable.php), control characters can trick redirect URL validation.
Technical Analysis
CVE-2017-6815 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
