FluentCart customers can control other customers' subscriptions

FluentCart before 1.4.0 fails to verify that a subscription identifier belongs to the authenticated customer in several payment-method operations. A customer who learns another subscription identifier can change its payment method, cancel it or re-bind it, crossing the account ownership boundary. The WPScan CNA record does not disclose the endpoint paths, identifier parameter, ownership-check function or payment providers affected.

CWE-284 — Improper Access Control

This CVE was published Jul 28, 2026 and is one of 1 known issue for this plugin.

Update, patch or deactivate.

Update FluentCart to 1.4.0 or later. Review subscription ownership, cancellations and payment-method changes for unexplained cross-account activity, and reconcile affected subscriptions with payment-provider records.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
