CVE-2026-120538 Overview
The Easy Digital Downloads plugin for WordPress is vulnerable to authentication bypass leading to administrator account takeover in all versions up to, and including, 3.7.2. During a PayPal guest checkout, the email address entered in the guest-checkout field is trusted as proof of identity: edd_get_purchase_form_user() binds the new guest order to an existing WordPress user purely on an email-address match, rewriting the order's user_id to that user's ID. The PayPal capture sink PurchaseUser::maybe_log_in_after_capture() then looked the user up by the order email (get_user_by( 'email', $order->email )) and, when $order->user_id equalled that user's ID (which the email-binding step guarantees), issued an authenticated session with wp_set_auth_cookie(). An unauthenticated attacker who starts a guest checkout using an administrator's email address (where that administrator has no existing EDD customer record) and completes the PayPal purchase flow therefore receives an authenticated session as that administrator — a full account takeover. The same sink is reachable through the standard PayPal checkout and the REST UnbrandedCard and Fastlane flows.

Related CVEs
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0, an unauthenticated token disclosure vulnerability in the MedEx callback endpoint allows any unauthenticated visitor to obtain the practice's MedEx API tokens, leading to complete third-party service compromise, PHI exfiltration, unauthorized actions on the MedEx platform, and HIPAA violations. The vulnerability exists because the endpoint bypasses authentication ($ignoreAuth = true) and performs a MedEx login whenever $_POST['callback_key'] is provided, returning the full JSON response including sensitive API tokens. This vulnerability is fixed in 8.0.0.
Improper authentication in Azure Resource Manager (ARM) allows an unauthorized attacker to elevate privileges over a network.
The vulnerability exists in BLUVOYIX due to improper authentication in the BLUVOYIX backend APIs. An unauthenticated remote attacker could exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable APIs. Successful exploitation of this vulnerability could allow the attacker to gain full access to customers' data and completely compromise the targeted platform.
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.2.10, an authentication bypass vulnerability in FUXA allows an unauthenticated, remote attacker to gain administrative access via the heartbeat refresh API and execute arbitrary code on the server. This issue has been patched in FUXA version 1.2.10.
Dokans Multi-Tenancy Based eCommerce Platform SaaS 3.9.2 allows unauthenticated remote attackers to obtain sensitive application configuration data via direct request to /script/.env file. The exposed file contains Laravel application encryption key (APP_KEY), database credentials, SMTP/SendGrid API credentials, and internal configuration parameters, enabling complete system compromise including authentication bypass via session token forgery, direct database access to all tenant data, and email infrastructure takeover. Due to the multi-tenancy architecture, this vulnerability affects all tenants in the system.
