Unauthenticated Broken Access Control in Knit Pay <= 9.4.0.0 versions.

AnalysisAI

Unauthenticated broken access control in the Knit Pay WordPress plugin versions 9.4.0.0 and earlier allows remote attackers to modify integrity-sensitive data without any authentication or user interaction. The flaw is rooted in missing authorization checks (CWE-862) on plugin endpoints, and while no public exploit identified at time of analysis, the network-reachable nature and zero prerequisites make it attractive for opportunistic abuse against WordPress sites running this payment plugin.

Technical ContextAI

Knit Pay is a WordPress payment-gateway plugin (CPE cpe:2.3:a:knit_pay:knit_pay) that integrates third-party Indian payment processors into WordPress sites. The underlying weakness is CWE-862 Missing Authorization, meaning one or more plugin actions - typically exposed via WordPress admin-ajax, REST routes, or admin-post handlers - execute privileged operations without verifying the caller's capability (current_user_can) or nonce. In WordPress plugins of this class, such gaps commonly surface in configuration, transaction-record, or webhook endpoints where the developer assumed an authenticated admin context but registered the hook on a public action.

RemediationAI

Upstream fix available (PR/commit); released patched version not independently confirmed from the provided data, so site operators should consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/knit-pay/vulnerability/wordpress-knit-pay-plugin-9-4-0-0-broken-access-control-vulnerability and update Knit Pay to any version greater than 9.4.0.0 as soon as the vendor publishes one on the WordPress.org plugin repository. As compensating controls until a patched release is verified, restrict access to /wp-admin/admin-ajax.php and the plugin's REST namespace via a WAF rule or .htaccess deny for unauthenticated callers (side effect: may break legitimate front-end checkout flows that rely on the plugin's AJAX handlers), deactivate the Knit Pay plugin if payment processing is not currently in production use, and audit recent plugin-related database writes for unauthorized modifications.
