Low risk13th percentile - higher than 13% of all known CVEs
Summary
The Koinonia Link WordPress plugin before 1.1.5 does not check that a user is allowed to change roles before saving a role selection submitted with a profile update, allowing any authenticated user, such as a subscriber, to grant themselves the Administrator role.
Risk Assessment
An authenticated user can escalate privileges to administrator level, potentially leading to full control of the WordPress site.
Recommendation
Immediately update the Koinonia Link plugin to version 1.1.5 or later and review user permissions.
