4.0
CVSS v3.1
Official Description
WordPress before 4.2.3 does not properly verify the edit_posts capability, which allows remote authenticated users to bypass intended access restrictions and create drafts by leveraging the Subscriber role, as demonstrated by a post-quickdraft-save action to wp-admin/post.php.
Technical Analysis
CVE-2015-5623 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
