CVE-2026-11462: BeikeShop Stripe Plugin Authorization Bypass (HIGH)

Technical summary

CVE-2026-11462 is an improper authorization vulnerability in the Stripe plugin component (plugins/Stripe/Controllers/StripeController.php) of BeikeShop. The vulnerability stems from insufficient authorization checks in the callback function, allowing attackers to manipulate the Request argument to bypass access controls. The flaw is rooted in authorization logic errors (CWE-266, CWE-285) and can be exploited over the network without authentication or user interaction. The CVSS 3.1 score of 7.3 (HIGH) reflects the combination of network accessibility, low complexity, and impact to confidentiality, integrity, and availability.

Business impact

Exploitation of this vulnerability could allow attackers to intercept or manipulate payment processing, potentially leading to unauthorized transactions, payment diversion, or compromise of customer financial data. For merchants using BeikeShop with Stripe integration, this represents a direct threat to transaction integrity and PCI-DSS compliance posture. Delayed patching exposes the organization to fraud, chargebacks, and reputational damage associated with payment system compromise.

Affected systems

BeikeShop versions up to and including 1.6.0.22 are affected. The vulnerability is specific to installations with the Stripe plugin enabled. Organizations running affected versions should prioritize inventory and testing immediately. Later versions may exist; verify your deployment version against vendor release notes.

Exploitability

This vulnerability is actively exploitable with low complexity. No authentication is required, no user interaction is necessary, and the attack surface is network-accessible. Public disclosure has occurred, increasing the likelihood of exploit development and scanning activity. The combination of these factors elevates real-world exploitation risk substantially.

Remediation

Apply the available patch immediately. The patch commit hash is 6719e0fc690ea0a998452092862e0f0a17c65968. Verify this commit hash against the official Chengdu Everbrite vendor repository or security advisory before deployment. If a formal version release is not yet available, coordinate with the vendor to obtain the patched code and test thoroughly in a staging environment before production rollout. As an interim measure, restrict network access to the Stripe callback endpoint if operationally feasible.

Patch guidance

Contact Chengdu Everbrite Network Technology for the official patch release corresponding to commit 6719e0fc690ea0a998452092862e0f0a17c65968. Apply patches to all BeikeShop instances running version 1.6.0.22 or earlier in your environment. Test the patch in a non-production environment that mirrors your production configuration, including payment processing workflows. Document the patching timeline and verify patch application using file integrity monitoring or version checks. Plan for a maintenance window to deploy the patch with minimal business disruption.

Detection guidance

Monitor web server access logs for requests to plugins/Stripe/Controllers/StripeController.php with unusual or manipulated Request parameters, particularly requests from untrusted IP ranges or with suspicious callback patterns. Implement intrusion detection signatures that flag attempts to bypass authorization in payment plugin code paths. Review Stripe transaction logs and payment processor reports for anomalous transactions, timeouts, or callback failures that may indicate exploitation attempts. Enable detailed logging on the Stripe plugin if available, and correlate application logs with network traffic analysis for behavioral indicators of post-exploitation activity.

Why prioritize this

This vulnerability merits immediate prioritization due to its HIGH CVSS score, active public exploit availability, direct impact on payment systems, and zero authentication requirements. Exploitation could result in direct financial loss and regulatory non-compliance. The combination of network accessibility and low attack complexity means opportunistic and targeted attackers alike can exploit unpatched instances with minimal effort.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) is driven by: network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), and impact to confidentiality, integrity, and availability (C:L/I:L/A:L). While the individual impacts are rated low, the unrestricted attack surface and zero-friction exploitation path elevate the overall risk to HIGH. The public disclosure and active exploit status further increase real-world severity.
