CVE-2026-2892

Περιγραφή

The Otter Blocks plugin for WordPress is vulnerable to Purchase Verification Bypass in all versions up to, and including, 3.1.4. This is due to the -get_customer_data- method relying on an unsigned -o_stripe_data- cookie to determine Stripe product ownership for unauthenticated users. The -check_purchase- method trusts this cookie data without performing server-side verification against the Stripe API for one-time -payment- mode purchases. This makes it possible for unauthenticated attackers to bypass Stripe purchase-gated content visibility conditions by forging the -o_stripe_data- cookie with a target product ID, which is publicly exposed in the checkout block-s HTML source.
