CVE-2026-11462: BeikeShop Auth Bypass Vulnerability

CVE-2026-11462 Overview

CVE-2026-11462 is an improper authorization vulnerability [CWE-266] affecting Chengdu Everbrite Network Technology BeikeShop up to version 1.6.0.22. The flaw resides in the callback function of plugins/Stripe/Controllers/StripeController.php within the Stripe Plugin component. Attackers can manipulate the Request argument to bypass authorization checks remotely without authentication or user interaction. The exploit has been disclosed publicly, increasing the risk of opportunistic abuse. The vendor has released patch commit 6719e0fc690ea0a998452092862e0f0a17c65968 to remediate the issue.

Critical Impact
Remote unauthenticated attackers can manipulate Stripe payment callback requests to perform unauthorized actions affecting confidentiality, integrity, and availability of the BeikeShop e-commerce platform.

Affected Products

Chengdu Everbrite Network Technology BeikeShop versions up to 1.6.0.22
BeikeShop Stripe Plugin component (plugins/Stripe/Controllers/StripeController.php)
Deployments of BeikeShop with Stripe payment processing enabled

Technical Details for CVE-2026-11462

Vulnerability Analysis

The vulnerability is classified as improper authorization [CWE-266] within the Stripe payment integration of BeikeShop. The callback function in StripeController.php processes incoming Stripe webhook or callback requests but fails to enforce sufficient authorization controls on the Request argument. An attacker can craft a request to the callback endpoint to invoke privileged actions reserved for legitimate payment confirmations.

Because BeikeShop is an e-commerce platform, the affected component handles transaction state transitions tied to financial operations. Successful exploitation can lead to unauthorized order manipulation, payment status changes, or access to data that the requester should not be permitted to read or modify.

Root Cause

The root cause is missing or insufficient verification of the caller's authorization context inside the Stripe callback handler. The function trusts attacker-controlled request parameters without validating that the caller has the privilege to trigger the underlying business logic. This is consistent with the CWE-266 classification of incorrect privilege assignment.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker sends a crafted HTTP request to the exposed Stripe callback endpoint, manipulating the Request parameters to bypass authorization. The exploit has been made public via a GitHub Vulnerability README, lowering the barrier to weaponization.

No verified code example is published in trusted advisories beyond the patch commit reference. Defenders should consult the GitHub Commit Update for the precise corrective changes applied by the maintainers.

Detection Methods for CVE-2026-11462

Indicators of Compromise

Unexpected HTTP requests targeting the Stripe callback route handled by plugins/Stripe/Controllers/StripeController.php
Order or payment status changes in BeikeShop with no matching legitimate Stripe webhook signature or transaction
Anomalous source IPs invoking the Stripe callback endpoint outside of Stripe's published IP ranges

Detection Strategies

Inspect web server access logs for repeated POST requests to the Stripe callback URL with malformed or unexpected parameters
Correlate BeikeShop order state transitions with corresponding Stripe API events to identify state changes lacking upstream confirmation
Alert on requests to the callback endpoint that fail signature validation or originate from non-Stripe networks

Monitoring Recommendations

Forward application and web server logs from BeikeShop deployments to a centralized analytics platform for review
Monitor for outbound traffic anomalies and database changes that follow suspicious callback requests
Enable alerting on privilege-sensitive operations executed through payment plugin code paths

How to Mitigate CVE-2026-11462

Immediate Actions Required

Apply the upstream patch commit 6719e0fc690ea0a998452092862e0f0a17c65968 from the BeikeShop repository
Restrict network access to the Stripe callback endpoint so that only Stripe IP ranges can reach it
Audit recent order and payment records for unauthorized state changes since the affected version was deployed

Patch Information

The maintainers released patch 6719e0fc690ea0a998452092862e0f0a17c65968, available in the GitHub Commit Update. Operators of BeikeShop versions up to 1.6.0.22 should update to a release containing this commit. Additional context is available in the VulDB CVE-2026-11462 record.

Workarounds

Disable the Stripe Plugin until the patch can be applied if Stripe processing is not actively required
Place a web application firewall rule in front of the callback route to validate request signatures and reject unauthorized callers
Enforce strict IP allowlisting to Stripe's documented webhook source ranges at the network edge

bash

# Example nginx restriction limiting access to Stripe callback endpoint
location ~ ^/plugins/Stripe/callback {
    allow 3.18.12.0/24;     # Stripe published range (verify current list)
    allow 3.130.192.0/24;   # Stripe published range (verify current list)
    deny all;
    proxy_pass http://beikeshop_backend;
