CVE-2026-89426

8.8 HIGH

Published 2026-09-25 · Updated 2026-09-25

AI risk analysis

Summary: The Knit Pay plugin for WordPress allows authenticated attackers with Subscriber-level access or higher to escalate their privileges to administrator by tampering with the role field in Gravity Forms entries.
Exploitability: Exploitation is relatively easy for authenticated users with Subscriber-level access or higher, as it requires only modifying the role field during form submission.
Blast radius: If exploited, the attacker could gain full administrative control over the WordPress site, leading to potential data breaches and unauthorized access to sensitive information.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Knit Pay version 9.6.2 or later.

NVD 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.
