Advisory
Source description from Wordfence Intelligence, credited to Karthik Ramakrishnan.
The SAML Single Sign On plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.4.7. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for unauthenticated attackers to elevate their privileges beyond those intended for their role.
