CVE-2026-84025 in BEAR Plugin
Summary
by MITRE • 09/12/2026
The BEAR WordPress plugin before 1.2.2 does not perform ownership checks on several handlers that return product data by a user-supplied identifier, allowing users who are restricted to their own products to read other owners' product information, including protected downloadable file URLs and private product metadata.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified in the BEAR WordPress plugin prior to version 1.2.2 represents a critical failure in access control mechanisms, specifically manifesting as an Insecure Direct Object Reference or Broken Access Control flaw. This issue stems from the application's inability to properly validate whether the authenticated user initiating a request has legitimate ownership rights over the specific resource being accessed. The plugin handles product data retrieval through several distinct handlers that accept identifiers supplied directly by the end-user, such as numeric IDs or unique slugs associated with products stored in the WordPress database. Under normal security expectations, these endpoints should enforce strict server-side checks to ensure that the requesting user's identity matches the owner of the requested product record. However, due to the absence of these ownership verification steps, the application blindly trusts the input identifier without cross-referencing it against the current session's permissions or the database records associated with the logged-in account.
This technical deficiency allows any authenticated user, regardless of their privilege level within the WordPress environment, to enumerate and retrieve data belonging to other users. By manipulating the product identifiers in API requests or direct HTTP calls, an attacker can systematically iterate through valid IDs to access a comprehensive list of products created by administrators or other contributors. The impact is particularly severe because BEAR deals with e-commerce functionality where sensitive commercial information is stored. Attackers are not limited to viewing basic public metadata; they can extract protected downloadable file URLs which may contain links to proprietary software, digital assets, or confidential documents intended only for specific customers. Furthermore, the exposure of private product metadata means that internal notes, pricing strategies, supplier details, and other non-public attributes become visible to unauthorized parties, leading to significant intellectual property theft and competitive disadvantage for affected businesses.
From a classification perspective, this vulnerability aligns with CWE-284, which describes Improper Access Control, as the system fails to restrict information retrieval based on user roles or ownership. It also maps directly to MITRE ATT&CK technique T1078, specifically Valid Accounts and potentially T1530 if used for data exfiltration from cloud-stored assets linked via those URLs. The operational impact extends beyond simple data leakage; it undermines the integrity of the e-commerce platform by allowing malicious actors to gather intelligence that could facilitate further attacks, such as targeted phishing campaigns using legitimate product details or supply chain compromises through exposed vendor information. In a multi-user WordPress environment where multiple vendors might operate on a single installation, this flaw effectively breaks the isolation between tenants, turning what should be private business data into publicly accessible resources for any registered user.
Mitigation strategies must prioritize immediate patching to version 1.2.2 or later, which addresses these access control gaps by implementing rigorous server-side validation logic. Developers and administrators should ensure that every endpoint returning sensitive product data performs a database query verifying that the product's owner ID matches the current user's ID before rendering any response. For environments where updating is not immediately feasible, temporary workarounds involve restricting access to the affected plugin endpoints via web application firewall rules or by disabling public API exposure for non-essential users until the patch is applied. Long-term remediation requires adopting a security-first development lifecycle that includes regular code audits focused on authorization checks and implementing principle of least privilege across all data retrieval operations within the WordPress ecosystem.
