MediumCVSS 5.3/10Last modified Sep 8, 2026

Description

The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.1.7 via the 'watch_checkout' function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to pay for a lower-cost product while obtaining entitlement for a premium product by manipulating the product_id parameter independently of the price_id parameter in the Stripe checkout URL.
