Technical Analysis
CVE-2026-87782 is an improper privilege management vulnerability (CWE-269) in the Koinonia Link WordPress plugin prior to version 1.1.5. The plugin fails to verify whether a user has permission to change roles before saving a role selection submitted during a profile update. This allows authenticated users with low privileges to escalate to the Administrator role.
Potential Impact
An attacker with any authenticated user account can elevate their privileges to Administrator, potentially gaining full control over the WordPress site. This can lead to unauthorized access, site takeover, and further malicious activities.
Mitigation Recommendations
Upgrade the Koinonia Link plugin to version 1.1.5 or later, where this privilege escalation vulnerability is fixed. Since no official patch links or advisories are provided, users should monitor the vendor's site or trusted plugin repositories for the update.
