{"schema":"threatline.record/2","record":{"id":"CVE-2026-89426","aliases":[],"summary":"Knit Pay <= 9.6.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms Role Field","details":"The Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.6.1.0. This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field — configured via the feed's `user_role_field_id` — and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` — the currently authenticated submitter's own user ID — making any authenticated form submitter an eligible exploitation target.","categories":["Unclassified"],"product":"Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more","vendor":"knitpay","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89426","source_modified_at":"2026-09-25T13:00:13.780Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more","vendor":"knitpay","versions":[{"version":"0","status":"affected","lessThanOrEqual":"9.6.1.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00475,"percentile":0.40141,"score_date":"2026-10-23"},"published_at":"2026-09-25T07:40:30.779Z","modified_at":"2026-09-25T13:00:13.780Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-89426","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T13:00:13.780Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-89426","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ee5df686-7bf8-42cc-9356-92570bd02355?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L384"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L381"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L989"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Processor.php#L493"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L384"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L381"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L989"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Processor.php#L493"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3706862%40knit-pay&new=3706862%40knit-pay"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-25T12:49:41.552995Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T13:00:13.780Z","content_hash":"94913ebc01c89c161827c921463a9a15ac5989eb0e4de3a293cc31f94fcea1b7"}}
