{"id":"CVE-2026-89426","state":"PUBLISHED","title":"Knit Pay <= 9.6.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms Role Field","description":"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.","publishedAt":"2026-09-25T07:40:30.779Z","updatedAt":"2026-09-25T13:00:13.780Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["knitpay Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more"],"affected":[{"vendor":"knitpay","product":"Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"9.6.1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ee5df686-7bf8-42cc-9356-92570bd02355?source=cve","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L384","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L381","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L989","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Processor.php#L493","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L384","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L381","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Extension.php#L989","https://plugins.trac.wordpress.org/browser/knit-pay/tags/9.4.0.1/packages/wp-pay-extensions/gravityforms/src/Processor.php#L493","https://plugins.trac.wordpress.org/changeset?reponame=&old=3706862%40knit-pay&new=3706862%40knit-pay"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/89xxx/CVE-2026-89426.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-89426","state":"PUBLISHED","datePublished":"2026-09-25T07:40:30.779Z","dateUpdated":"2026-09-25T13:00:13.780Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-11T18:34:23.074Z"},"containers":{"cna":{"title":"Knit Pay <= 9.6.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms Role Field","descriptions":[{"lang":"en","value":"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.
