Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker with at least Subscriber-level access to take over any user's account by changing their email address and triggering a password reset, effectively giving themselves full administrator privileges. The attacker only needs to know the donor ID of the target account to exploit this flaw.

Technical Description

The IDonate – Blood Donation, Request And Donor Management System plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the idonate_donor_profile() function in versions 2.1.5 to 2.1.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to hijack any account by reassigning its email address (via the donor_id they supply) and then triggering a password reset, ultimately granting themselves full administrator privileges.
