CVE-2026-57424 Overview
CVE-2026-57424 is a missing authorization vulnerability in the knitpay Razorpay Payment Links for WooCommerce plugin (rzp-woocommerce) for WordPress. The flaw affects all plugin versions up to and including 2.1.4. Attackers can exploit incorrectly configured access control checks to interact with plugin functionality that should require elevated privileges. The vulnerability is tracked under CWE-862: Missing Authorization and is reachable over the network without authentication or user interaction.
Critical Impact
Unauthenticated network attackers can abuse plugin endpoints protected by insufficient access control, leading to limited integrity and availability impact on WooCommerce stores using vulnerable Razorpay Payment Link integrations.
Affected Products
- knitpay Razorpay Payment Links for WooCommerce (rzp-woocommerce) plugin
- All versions from n/a through 2.1.4
- WordPress sites running WooCommerce with this plugin enabled

Technical Details for CVE-2026-57424
Vulnerability Analysis
The Razorpay Payment Links for WooCommerce plugin exposes functionality without enforcing appropriate capability or nonce checks. Endpoints that perform state-changing or sensitive read operations rely on incorrectly configured access control levels. As a result, requests that should be restricted to authenticated privileged users can be issued by unauthenticated clients over HTTP or HTTPS.
The EPSS score at publication is 0.242%, indicating a low near-term exploitation probability. However, WordPress e-commerce plugins are frequently targeted once details enter public vulnerability databases such as Patchstack.
Root Cause
The root cause is a missing authorization check on one or more plugin actions. WordPress plugins typically enforce authorization through current_user_can() capability checks combined with nonce validation via check_admin_referer() or wp_verify_nonce(). In rzp-woocommerce versions up to 2.1.4, at least one handler executes privileged logic without validating that the caller holds the required capability, matching the [CWE-862] pattern.
Attack Vector
An unauthenticated attacker sends crafted HTTP requests to the affected plugin endpoint on a vulnerable WordPress site. Because privileges are not required and no user interaction is involved, exploitation can be scripted at scale against WooCommerce stores. The impact is limited to integrity and availability of plugin-managed data such as payment link configuration, without direct confidentiality exposure.
No verified public proof-of-concept is currently available. See the Patchstack Vulnerability Report for advisory details.
Detection Methods for CVE-2026-57424
Indicators of Compromise
- Unexpected HTTP POST or GET requests to rzp-woocommerce plugin endpoints from unauthenticated sessions or unknown IP addresses.
- Modifications to Razorpay payment link configurations, WooCommerce orders, or plugin options without a corresponding administrator audit trail.
- Spikes in admin-ajax.php or REST API traffic referencing plugin-specific actions outside normal business hours.
Detection Strategies
- Review WordPress and web server access logs for requests to plugin endpoints lacking a valid authenticated session cookie or _wpnonce parameter.
- Compare current plugin settings and payment link records against known-good baselines to identify unauthorized changes.
- Correlate WooCommerce order state transitions with administrator identity to flag actions performed without an associated logged-in user.
Monitoring Recommendations
- Enable verbose logging on the WordPress installation and forward logs to a centralized SIEM or data lake for retention and correlation.
- Alert on 200-response codes to plugin endpoints when the request originates from anonymous clients.
- Monitor outbound calls from the WordPress host to the Razorpay API for anomalies in volume or destination.
How to Mitigate CVE-2026-57424
Immediate Actions Required
- Identify all WordPress sites running the rzp-woocommerce plugin at version 2.1.4 or earlier and prioritize them for remediation.
- Restrict administrative and plugin endpoints via web application firewall rules that require authenticated sessions.
- Rotate WooCommerce and Razorpay API credentials if unauthorized configuration changes are suspected.
Patch Information
At the time of publication, refer to the Patchstack Vulnerability Report for the latest fixed version guidance. Upgrade to a release later than 2.1.4 once published by the plugin vendor knitpay.
Workarounds
- Temporarily deactivate the rzp-woocommerce plugin until a fixed version is installed.
- Deploy WAF virtual patching rules that block unauthenticated requests to the plugin's action handlers.
- Restrict access to /wp-admin/admin-ajax.php and plugin REST routes by IP allowlist where feasible.
