CVE-2025-49987: WPFactory CRM ERP Auth Bypass Vulnerability

CVE-2025-49987 Overview

CVE-2025-49987 is a missing authorization vulnerability in the WPFactory CRM ERP Business Solution plugin for WordPress. The flaw affects crm-erp-business-solution versions up to and including 1.13. The plugin fails to enforce access control checks on functionality that should be restricted to authorized users. Unauthenticated attackers can invoke protected actions across the network without any user interaction. The weakness is classified under [CWE-862] Missing Authorization. Successful exploitation can lead to limited integrity impact on affected WordPress installations that host business, customer, or sales data managed through the plugin.

Critical Impact
Unauthenticated attackers can reach functionality that lacks proper access control, allowing modification of plugin-managed data over the network.

Affected Products

WPFactory CRM ERP Business Solution (crm-erp-business-solution) plugin for WordPress
All versions from initial release through 1.13
WordPress sites running the affected plugin with default configuration

Technical Details for CVE-2025-49987

Vulnerability Analysis

The vulnerability stems from broken access control in the CRM ERP Business Solution plugin. One or more plugin actions do not verify the caller's capability or role before executing sensitive operations. An attacker sends crafted HTTP requests to plugin endpoints and reaches functionality that should require authenticated privileged access. The impact is limited to integrity, meaning attackers can modify certain data managed by the plugin but cannot directly read confidential records or trigger denial of service. Because the plugin manages customer relationship and enterprise resource planning data, tampering with plugin objects can distort business records and downstream workflows.

Root Cause

The root cause is a missing authorization check ([CWE-862]) on one or more plugin request handlers. WordPress plugins are expected to validate capabilities using functions such as current_user_can() and to verify request authenticity with nonces via check_admin_referer() or wp_verify_nonce(). In crm-erp-business-solution through 1.13, these checks are absent or incorrectly configured for at least one action, exposing privileged functionality to unauthorized callers.

Attack Vector

Exploitation occurs remotely over HTTP or HTTPS with no privileges and no user interaction. An attacker crafts a request directly to the vulnerable plugin endpoint on the target WordPress site. The server processes the request without verifying the caller's identity or capabilities. Refer to the Patchstack Vulnerability Report for endpoint-specific technical details.

Detection Methods for CVE-2025-49987

Indicators of Compromise

Unexpected modifications to CRM or ERP records stored by the plugin, including new or altered customer, invoice, or product entries.
HTTP requests to plugin action handlers originating from unauthenticated sessions or unknown source IP addresses.
WordPress access logs showing repeated POST or GET requests to admin-ajax.php or plugin routes with crm-erp-business-solution action parameters.

Detection Strategies

Inventory WordPress installations and identify sites running crm-erp-business-solution at version 1.13 or earlier.
Review web server access logs for anomalous request patterns targeting plugin endpoints without prior authenticated sessions.
Correlate database changes in plugin tables with the authenticated user activity recorded in the WordPress audit trail.

Monitoring Recommendations

Enable verbose logging on the WordPress application and forward logs to a centralized analytics platform for retention and query.
Alert on plugin action invocations from IP addresses that have not completed an authentication flow.
Monitor the Patchstack Vulnerability Report for updated indicators and patch availability.

How to Mitigate CVE-2025-49987

Immediate Actions Required

Identify all WordPress deployments running crm-erp-business-solution and confirm the installed version.
Restrict access to WordPress administrative and AJAX endpoints using IP allowlists or a web application firewall (WAF) until a patch is applied.
Audit plugin-managed data for unauthorized modifications and preserve logs for incident investigation.

Patch Information

At the time of publication, the vendor advisory tracked by Patchstack lists affected versions from initial release through 1.13. Review the Patchstack Vulnerability Report for the latest fixed version and update the plugin through the WordPress admin dashboard or WP-CLI as soon as a patched release is available.

Workarounds

Deactivate and remove the CRM ERP Business Solution plugin on sites where it is not business-critical until a fixed version is installed.
Deploy WAF rules that block unauthenticated requests to plugin AJAX and REST endpoints associated with crm-erp-business-solution.
Enforce least privilege on WordPress accounts and require multi-factor authentication for administrator and editor roles.

bash

# Configuration example: identify affected installations using WP-CLI
wp plugin list --name=crm-erp-business-solution --fields=name,status,version

# Deactivate the vulnerable plugin until a patched release is applied
wp plugin deactivate crm-erp-business-solution
