Description

WordPress is prone to a directory traversal vulnerability because it fails to sufficiently verify user-supplied input data. Exploiting this issue may allow an attacker to access sensitive information that could aid in further attacks or to cause the affected website to consume resources, thus denying service to legitimate users. WordPress version 4.5.3 is vulnerable.

Remediation

Update to WordPress version 4.6 or latest
