Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The IDonate WordPress plugin versions 2.1.5-2.1.9 lacks a capability check in the idonate_donor_profile() function, allowing authenticated subscribers to reassign any user's email address and trigger password resets to hijack administrator accounts.

MitigationUpdate to the latest plugin version once patched, or add a capability check (e.g., manage_options) to the idonate_donor_profile() function and restrict email reassignment to administrative users only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify IDonate plugin installation and version
    Navigate to WordPress admin > Plugins, locate IDonate plugin, and note the installed version number. Alternatively, check the plugin header in wp-content/plugins/idonate/plugin.php for 'Version:' field.
    Affected if The installed version is 2.1.5, 2.1.6, 2.1.7, 2.1.8, or 2.1.9.
  2. Locate the vulnerable function
    Open the plugin file containing idonate_donor_profile() function, typically in includes or core plugin files. Search for 'function idonate_donor_profile'.
    Affected if The function exists in the installed plugin version.
  3. Inspect for missing capability check
    Examine the idonate_donor_profile() function body. Look for a call to current_user_can() with an administrative capability (such as 'manage_options') before any email or donor ID modification logic.
    Affected if The function lacks a current_user_can() check or only checks for a low-privilege capability (like 'read') before allowing email reassignment.
  4. Identify exploitable user roles
    In WordPress admin > Users, review the list of registered users and their assigned roles. Note any users with 'Subscriber' role.
    Affected if There is at least one user account with Subscriber role, as this role level can exploit the vulnerability.

You are affected if IDonate plugin versions 2.1.5-2.1.9 are installed, the idonate_donor_profile() function lacks a capability check like current_user_can('manage_options'), and at least one Subscriber-level user account exists in WordPress.
