CVE-2026-10820 · Severity: info · CVSS 8.1 · Published 2026-06-27

A vulnerability in the ProfilePress WordPress plugin allows any logged-in user to cancel the active subscriptions of other members. In some cases, this can result in the victim's account permissions being removed and the cancellation being sent to payment processors, making the damage difficult to undo. Because subscription IDs are predictable, an attacker could potentially automate the cancellation of every active membership on a site, leading to significant revenue loss and operational disruption.

## Technical details

An Insecure Direct Object Reference (IDOR) exists in the ProfilePress plugin (formerly WP User Avatar) before version 4.16.17. The application fails to validate that the user requesting a subscription cancellation is the actual owner of that subscription. Since subscription IDs are sequential integers, an authenticated attacker (with Subscriber-level permissions or higher) can enumerate and cancel active subscriptions across the entire platform. For lifetime plans, this action also removes the victim's WordPress role. If a payment gateway is integrated, the cancellation is propagated to the external provider, complicating recovery efforts. The vulnerability is rooted in missing ownership checks within the subscription management logic.
