CVE-2026-84025: BEAR WordPress Plugin Information Disclosure

CVE-2026-84025 Overview

CVE-2026-84025 affects the BEAR WordPress plugin in versions prior to 1.2.2. The plugin fails to enforce ownership checks on several handlers that return product data based on a user-supplied identifier. Authenticated users who are restricted to managing only their own products can read other owners' product records by supplying arbitrary product IDs. Exposed data includes protected downloadable file URLs and private product metadata. The weakness is classified as an Insecure Direct Object Reference [CWE-639].

Critical Impact
Authenticated vendors can enumerate and disclose other vendors' private product metadata and protected download URLs, breaking multi-vendor tenant isolation in the BEAR plugin.

Affected Products

BEAR WordPress plugin versions prior to 1.2.2
WordPress sites operating multi-vendor product catalogs through BEAR
Deployments granting non-administrative users vendor-level access to BEAR

Technical Details for CVE-2026-84025

Vulnerability Analysis

The BEAR plugin exposes several handlers that accept a product identifier from the request and return product data without verifying that the requesting user owns the referenced product. Any authenticated account holding the vendor role can pass another vendor's product ID and receive that vendor's data. The response payload includes private product metadata and protected downloadable file URLs that are intended to remain scoped to the owning account. Because the plugin trusts the client-supplied identifier as an authorization signal, the tenancy boundary between vendor accounts collapses at the handler layer.

Root Cause

The root cause is missing authorization enforcement on identifier-driven handlers, aligned with [CWE-639] Authorization Bypass Through User-Controlled Key. The handlers perform request validation and role checks sufficient to confirm the caller is a vendor, but they do not confirm that the caller owns the record referenced by the supplied ID. The lookup query is executed against the product store using the raw ID, and the resulting record is serialized to the response regardless of ownership.

Attack Vector

Exploitation requires an authenticated account with the vendor-scoped role that the plugin normally restricts to a user's own products. The attacker iterates or guesses numeric product identifiers and issues requests to the affected handlers. The server returns the requested product records, including protected download URLs and private metadata, which the attacker can then harvest or redistribute. No user interaction from the victim vendor is required.

No verified proof-of-concept is published. Technical details are described in the WPScan Vulnerability Report.

Detection Methods for CVE-2026-84025

Indicators of Compromise

Sequential or enumerated product identifiers submitted by a single authenticated vendor account to BEAR product data handlers.
Vendor accounts issuing high-volume requests for product records they do not own.
Access logs showing successful HTTP 200 responses for product IDs outside the caller's normal working set.

Detection Strategies

Correlate WordPress authentication events with plugin handler requests to identify vendors requesting other owners' product IDs.
Baseline each vendor account's typical product ID range and alert on deviations that suggest enumeration.
Inspect outbound responses from BEAR endpoints for downloadable file URLs delivered to accounts other than the owning vendor.

Monitoring Recommendations

Enable verbose WordPress and web server access logging for BEAR plugin endpoints.
Forward WordPress and web server telemetry to a centralized analytics platform for cross-account correlation.
Track the ratio of unique product IDs requested per session to surface enumeration behavior early.

How to Mitigate CVE-2026-84025

Immediate Actions Required

Upgrade the BEAR WordPress plugin to version 1.2.2 or later on all affected sites.
Audit vendor accounts for anomalous product data access preceding the upgrade window.
Rotate or invalidate protected downloadable file URLs that may have been disclosed to unauthorized vendors.

Patch Information

The vendor addresses the issue in BEAR version 1.2.2 by enforcing ownership checks on the affected product data handlers. Refer to the WPScan Vulnerability Report for advisory details and the fix reference.

Workarounds

Restrict vendor-role account creation until the plugin is upgraded to 1.2.2.
Place BEAR handler routes behind a web application firewall rule that constrains product ID parameters to values associated with the authenticated user where feasible.
Temporarily disable the BEAR plugin on sites where an immediate upgrade is not possible and vendor separation is critical.

bash

# Update the BEAR plugin using WP-CLI
wp plugin update bear --version=1.2.2
wp plugin list --name=bear --fields=name,status,version
