CVE-2026-92458 in yshop-crm
Summary
by MITRE • 09/16/2026
yshop-crm through 2.1.3 contains a missing authorization vulnerability in the StoreProductController onSale handler that allows authenticated back-office users to modify product sale status. Attackers can invoke the GET /admin-api/product/store-product/sale endpoint with sequential product IDs to withdraw entire product catalogs from sale or re-enable withdrawn products without proper permission checks.

The vulnerability identified in yshop-crm versions through 2.1.3 represents a critical failure in access control mechanisms, specifically classified under CWE-862 as Missing Authorization. This flaw resides within the StoreProductController's onSale handler, which is designed to manage the active status of products within an e-commerce platform. The core technical issue stems from the application's inability to verify whether the authenticated user initiating a request possesses the specific administrative privileges required for that action. While the system correctly authenticates users and restricts access to the /admin-api/product/store-product/sale endpoint based on general login credentials, it fails to implement granular role-based checks or object-level permissions when processing requests to modify product states. This architectural oversight allows any user with valid back-office authentication credentials to bypass intended restrictions and execute state-changing operations that should be reserved for higher-privileged administrators.
The operational impact of this vulnerability is significant due to the ease of exploitation via automated sequential ID enumeration. Attackers can leverage simple scripting tools to iterate through product identifiers, sending GET requests to the vulnerable endpoint with varying IDs in rapid succession. This technique enables the mass modification of product sale statuses across the entire catalog without manual intervention or specific targeting. By withdrawing products from sale, an attacker can effectively disrupt business operations by hiding inventory from customers, leading to direct revenue loss and potential damage to brand reputation through perceived site instability. Conversely, re-enabling withdrawn products can introduce unauthorized items into the marketplace, potentially facilitating fraud, selling counterfeit goods, or exposing sensitive product data that was intended to be removed due to compliance issues or errors. The lack of rate limiting on this endpoint further exacerbates the risk by allowing high-volume automated attacks that are difficult for standard intrusion detection systems to flag as malicious activity compared to more obvious injection attempts.
From a threat modeling perspective, this vulnerability aligns with MITRE ATT&CK technique T1078, specifically Valid Accounts and potentially T1534 if used in conjunction with internal network pivoting, although the primary vector here is direct web exploitation via valid credentials. The absence of proper authorization checks means that lateral movement within the application's functional scope becomes trivial for any compromised or low-privilege account holder. To mitigate this risk, developers must implement strict role-based access control (RBAC) policies at the controller level, ensuring that only users with designated administrative roles can invoke methods that alter critical business data such as product availability. Additionally, implementing object-level authorization checks is essential to verify that each specific request targets a resource for which the user has explicit permission. Security controls should also include comprehensive logging of all state-change operations on sensitive entities like products, enabling security teams to detect anomalous patterns indicative of automated enumeration attacks. Regular penetration testing focused on broken access control scenarios and adherence to OWASP API Security Top 10 guidelines will help prevent similar vulnerabilities in future releases.
