CVE-2026-49081Network attack vector

Payment manipulation via unverified Stripe intent

Published Jun 17, 2026 · Updated Jun 17, 2026

Broken access control in ThemeGrill User Registration Stripe 1.3.12 and earlier allows remote attackers to manipulate payment processing. Affected payment handling does not verify the Stripe PaymentIntent and lacks a nonce check, according to the vendor changelog. Authentication is not required; public sources do not identify the affected endpoint or exact unauthorized action, limiting impact triage to payment-data confidentiality and integrity.
