CVE-2026-56025: Paymob for WooCommerce Auth Bypass Flaw

CVE-2026-56025 Overview

CVE-2026-56025 is an unauthenticated broken access control vulnerability affecting the Paymob for WooCommerce WordPress plugin in versions up to and including 4.1.2. The flaw stems from a missing authorization check [CWE-862] that allows remote attackers to reach protected plugin functionality without credentials. Because the plugin integrates payment processing into WooCommerce storefronts, exploitation can tamper with order or payment integrity on affected sites. The vulnerability is exploitable over the network with low attack complexity and no user interaction.

Critical Impact
Unauthenticated attackers can invoke restricted Paymob for WooCommerce functionality over the network, compromising the integrity of payment or order data on affected WordPress sites.

Affected Products

Paymob for WooCommerce WordPress plugin versions <= 4.1.2
WordPress sites running WooCommerce with the Paymob integration enabled
E-commerce deployments exposing the vulnerable plugin endpoints to the internet

Technical Details for CVE-2026-56025

Vulnerability Analysis

The vulnerability is a Broken Access Control weakness classified under [CWE-862] Missing Authorization. The Paymob for WooCommerce plugin exposes functionality that fails to verify whether the requester holds the required privileges before executing sensitive operations. An unauthenticated attacker can send a crafted HTTP request directly to the vulnerable endpoint and trigger actions that should be restricted to authorized users or the payment gateway itself.

The impact profile is integrity-focused. Successful exploitation does not directly disclose sensitive data or crash the site, but it enables unauthorized modification of state managed by the plugin. In a payment plugin, that typically includes order status, payment confirmation, or callback-driven fields tied to transaction records. See the Patchstack advisory for coordinated disclosure details.

Root Cause

The root cause is a missing capability or nonce check on one or more plugin request handlers. WordPress plugins are expected to gate privileged actions with current_user_can() checks, capability-based REST permission callbacks, or validated payment gateway signatures. In the affected versions, this authorization layer is absent or insufficient on the exposed endpoint.

Attack Vector

The attack vector is network-based and unauthenticated. An attacker sends an HTTP request to the vulnerable Paymob for WooCommerce endpoint on a target WordPress site. Because no privileges or user interaction are required, the request can be automated and scaled across many sites running the plugin. No verified proof-of-concept code is publicly available. Refer to the Patchstack vulnerability entry for technical details as they are published.

Detection Methods for CVE-2026-56025

Indicators of Compromise

Unexpected changes to WooCommerce order status or payment state without a corresponding customer checkout flow
HTTP requests to Paymob for WooCommerce plugin endpoints originating from IP addresses outside the legitimate Paymob gateway ranges
Repeated unauthenticated POST requests to plugin routes under /wp-json/ or /?wc-api= handlers associated with Paymob
Order records referencing transaction identifiers that do not match Paymob's backend records

Detection Strategies

Enable WordPress and WooCommerce audit logging to record order status transitions and their originating request context
Correlate web server access logs with WooCommerce order events to identify state changes without a preceding authenticated checkout session
Alert on unauthenticated requests to Paymob plugin routes that return HTTP 200 outside expected gateway callback sources

Monitoring Recommendations

Monitor edge and WAF telemetry for anomalous request volumes targeting paymob or wc-api paths
Track order-to-payment reconciliation gaps between WooCommerce and the Paymob merchant dashboard on a daily cadence
Ingest WordPress, web server, and WAF logs into a centralized data lake to support cross-source correlation of exploitation attempts

How to Mitigate CVE-2026-56025

Immediate Actions Required

Identify all WordPress sites running Paymob for WooCommerce and confirm the installed version
Update the plugin to a version later than 4.1.2 as soon as a fixed release is published by the vendor
Reconcile recent WooCommerce orders against Paymob transaction records to detect tampering
Restrict access to plugin callback endpoints at the WAF or reverse proxy to known Paymob source addresses where feasible

Patch Information

The vulnerability affects Paymob for WooCommerce versions <= 4.1.2. Administrators should upgrade to the patched release referenced in the Patchstack advisory. Confirm the fixed version directly with the plugin vendor before deploying.

Workarounds

Temporarily deactivate the Paymob for WooCommerce plugin until a patched version is installed
Apply WAF rules that block unauthenticated requests to Paymob plugin endpoints from sources outside the payment gateway's published IP ranges
Enforce HTTP method allowlists on affected routes to reduce the exposed attack surface

bash

# Example WAF rule concept: restrict Paymob callback endpoint to gateway IPs
# Replace 203.0.113.0/24 with Paymob's published source ranges
location ~* /(wp-json/paymob|\?wc-api=paymob) {
    allow 203.0.113.0/24;
    deny all;
}
