• Product Name: IDonate – Blood Donation, Request And Donor Management System plugin for WordPress
• Published Date: November 22, 2025
• Severity: Medium
• Status: Analyzed

Affected Products

The vulnerability specifically impacts all versions of the IDonate – Blood Donation, Request And Donor Management System plugin for WordPress up to, and including, version 2.1.15. If your WordPress site is running any version within this range, it is susceptible to this flaw. It is crucial to verify your plugin version and take immediate action if you are using an affected release.

Current Status

The vulnerability has been thoroughly analyzed, and its details have been made public. This means that the issue is well-understood, and the plugin developers have been able to release updates to address it. Public disclosure also means that potential attackers are aware of the vulnerability, increasing the urgency for users to patch their systems.

Severity Level

With a “Medium” severity rating, CVE-2025-12877 poses a notable risk. The primary impact of this flaw is the ability for unauthenticated attackers to delete arbitrary posts on your WordPress site. “Unauthenticated” means that an attacker does not need to have a user account, password, or any specific login credentials to carry out this action. This lack of authentication requirement makes the vulnerability particularly concerning, as it broadens the pool of potential attackers. The deletion of posts can lead to significant disruption, loss of valuable content, and damage to your website’s reputation and SEO. While it doesn’t grant full administrative control, the impact on content integrity is substantial.

Possible Solutions

The root cause of this vulnerability was a missing capability check in the plugin’s panding_blood_request_action() function. Essentially, this function, which can perform actions like deleting posts, was accessible without proper authorization checks. The fix involves two main components:

1. Capability Check Implementation: A robust capability check has been added to the panding_blood_request_action() function. This ensures that only users with the necessary permissions (specifically, the delete_posts capability) can initiate actions through this function.
2. Removal of Unauthenticated Access: The wp_ajax_nopriv_panding_blood_request_action hook, which allowed non-logged-in users to interact with this function, has been removed.

To protect your WordPress site from this vulnerability, the most critical step is to update the IDonate – Blood Donation, Request And Donor Management System plugin to its latest available version immediately. Plugin developers release updates to address such security issues, and applying these updates is your best defense. Before updating any plugin, it is always a good practice to create a full backup of your website. Beyond this specific patch, maintaining a proactive security posture, including regular updates for all software, strong passwords, and security monitoring, is essential for overall website safety.
