{"cve":"CVE-2026-2892","nvd":{"published":"2026-04-30T14:16:29.760","modified":"2026-06-17T10:31:58.880","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-285"],"references":["https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-block-conditions.php#L274","https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-stripe-api.php#L260","https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-stripe-api.php#L284","https://plugins.trac.wordpress.org/changeset/3471326/","https://www.wordfence.com/threat-intel/vulnerabilities/id/3443950f-1f94-4e0b-8906-1a9b9602a746?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-2892","score":0.0032,"percentile":0.24991,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
