SureForms – Drag and Drop Form Builder for WordPress versions up to and including 2.2.1 contains an improper input validation vulnerability. The plugin accepts payment amounts directly from user-controlled POST data in certain payment intent functions without verifying against the configured form price. This allows unauthenticated attackers to modify payment amounts arbitrarily when submitting Stripe payment forms, potentially enabling purchases at reduced prices.
AI Analysis
Technical Summary
CVE-2026-15288 is an improper input validation vulnerability (CWE-20) in the SureForms WordPress plugin up to version 2.2.1. The vulnerability arises because the plugin's 'create_payment_intent' and 'create_subscription_intent' functions accept payment amounts directly from user POST data without validating them against the form's configured price. This flaw allows unauthenticated attackers to manipulate payment amounts submitted via Stripe payment forms, potentially bypassing intended pricing controls.
Potential Impact
An attacker can submit arbitrary payment amounts when using Stripe payment forms, potentially purchasing products or services at significantly reduced prices. This compromises the integrity of payment processing but does not directly affect confidentiality or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling the affected payment functionality or applying custom validation to ensure payment amounts match configured prices.
