CVE-2026-66476

Easy Digital Downloads plugin version 3.6.7 and earlier contains a broken authentication vulnerability that does not require authentication. An attacker can gain unauthorized access to administrative functions.

The Easy Digital Downloads plugin for WordPress up to version 3.6.9 is vulnerable to Stored Cross-Site Scripting (XSS) via PayPal IPN parameters. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary web scripts that execute when a user accesses an injected page.

The Easy Digital Downloads WordPress plugin before 3.7.1 does not consult the site's user registration setting before creating a WordPress account, allowing unauthenticated users to create an account and receive a logged-in session even when registration is disabled. The created account receives the site's default role.

The Easy Digital Downloads WordPress plugin before 3.7.1 does not restrict a block's order data to the current user, allowing users with subscriber-level access to view other customers' recent order products and obtain signed download links that grant access to paid digital files without purchase.

Missing Authorization vulnerability in Easy Digital Downloads allows exploiting incorrectly configured access control security levels. Affects versions through 3.7.1.

The Easy Digital Downloads plugin in versions up to and including 3.7.0 contains an SQL Injection vulnerability accessible to users with the Shop manager role. This allows injection of malicious SQL code into database queries.

The Easy Digital Downloads plugin for WordPress up to version 3.6.9 allows arbitrary file upload. The `edd_do_ajax_import_file_upload()` function only checks the client-supplied Content-Type header and saves the file with its original extension to a web-accessible directory. Authenticated attackers with Shop Manager access can upload arbitrary files, potentially leading to remote code execution.

Easy Digital Downloads versions up to 3.6.5 have a vulnerability in access control that allows unauthorized access to resources.

The Easy Digital Downloads plugin for WordPress in all versions up to and including 3.5.2 is vulnerable to Order Manipulation due to an order verification bypass. When the POST body includes verification_override=1, verification is unconditionally skipped, allowing an unauthenticated attacker to submit a forged IPN that is treated as verified. A valid PayPal transaction id is required, restricting order manipulation to orders placed by the attacker with a customer account.
