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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["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#L384","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/browser/knit-pay/tags/9.6.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L381"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-89426","score":0.00462,"percentile":0.4003,"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).
