What the vulnerability does

01Description

The Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Insecure Direct Object Reference / Authorization Bypass leading to Arbitrary Attachment Deletion in versions up to, and including, 1.8.11.1 via the profile avatar update flow. This is due to the save_avatar() function in Charitable_Profile_Form calling wp_delete_attachment() on an attachment ID read from the user's 'avatar' meta without validating that the attachment is owned by the user, combined with Charitable_Data_Processor::process_picture() returning the raw posted value when no file is uploaded, allowing the 'avatar' user meta to be poisoned with any attacker-chosen attachment ID. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary attachments from the Media Library by performing a two-request chain (first poisoning the stored avatar meta value with a target attachment ID, then triggering deletion via a normal avatar upload).

Explanation of Vulnerability in Simple Terms

02Summary

The Charitable donation plugin for WordPress contains an authorization flaw affecting versions up to 1.8.11.1. An authenticated user with low privileges can modify donation data or plugin settings they should not have access to. The vulnerability requires a valid WordPress account but no special interaction.
