CVE-2025-4521

8.8 · HIGH
Published Feb 19, 2026 CWE-285

Overview

CVE-2025-4521 is a high-severity vulnerability. It was published on February 19, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
