Description

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.

  "executiveSummary": "The BEAR WordPress plugin, in versions prior to 1.2.2, is affected by a broken access control vulnerability. This flaw manifests as a lack of proper ownership validation within specific data-handling functions. Consequently, authenticated users—even those constrained by lower privilege levels intended to restrict them to their own content—can access sensitive data belonging to other users. The vulnerability poses a significant security risk by facilitating unauthorized disclosure of proprietary product information. An attacker with standard authenticated access can successfully exploit this by manipulating user-supplied identifiers in requests, bypassing intended security boundaries. The impact includes the exposure of private product metadata and sensitive protected downloadable file URLs, potentially leading to unauthorized data harvesting or intellectual property theft.\nThis vulnerability highlights a critical failure in enforcing authorization policies on the backend. Because the application fails to verify whether a requested resource ID belongs to the authenticated user, any user can traverse and extract information from the entire product catalog, regardless of administrative or ownership constraints. The risk is high given that the exploitation does not require advanced technical sophistication, only the ability to supply arbitrary identifiers to the affected handlers.",
  "technicalDetails": "The root cause of the vulnerability lies in the improper implementation of authorization checks within the BEAR plugin's request handlers. Specifically, the plugin features several backend handlers designed to retrieve product data based on a user-supplied identifier. In a secure architecture, these handlers must strictly validate that the authenticated user maintains ownership or sufficient administrative privileges over the requested object before returning the dataset. In affected versions, this validation step is entirely omitted.\nThe attack flow begins when an authenticated user—who is intended to be restricted to their own products—sends a crafted request to the vulnerable plugin handler. By modifying the product ID parameter within the HTTP request, the user directs the handler to fetch records that fall outside their authorized scope. Because the backend code assumes the request is valid without performing an authorization check against the database record's owner field, it proceeds to serialize and return the requested product data to the attacker.\nThe vulnerability affects all BEAR WordPress plugin versions prior to 1.2.2. The impacted component is the set of data-fetching handlers that process user-supplied identifiers. Exploitation requires the attacker to be authenticated as a standard user with at least some basic access to the plugin's functionality. There is no requirement for high-level administrative privileges; the vulnerability is accessible through the standard user interface or direct API requests.\nTechnically, the payload behavior involves an Insecure Direct Object Reference (IDOR) pattern. When the handler receives an arbitrary product ID, it executes a database query to retrieve the object. The resulting JSON or data structure returned to the client contains metadata that should remain private. This includes the internal system paths for protected downloadable files and proprietary product metadata that is otherwise hidden from unauthorized users. Post-exploitation, an attacker can systematically enumerate product IDs to scrape the entire inventory's private details, leading to the unauthorized disclosure of protected URLs. These URLs can then be used to access files that the user should not have permission to download, bypassing the intended security controls of the WordPress e-commerce environment."
