CVE-2025-62754: bKash for WC Auth Bypass Vulnerability

CVE-2025-62754 Overview

CVE-2025-62754 is a Missing Authorization vulnerability (CWE-862) affecting the Payment Gateway bKash for WC WordPress plugin (woo-payment-bkash) developed by Kapil Paul. This broken access control vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially gaining unauthorized access to payment gateway functionality and sensitive transaction data.

Critical Impact

This vulnerability enables attackers to bypass authorization checks in a WooCommerce payment gateway plugin, potentially allowing unauthorized access to payment processing functions and customer financial data.

Affected Products

• Payment Gateway bKash for WC (woo-payment-bkash) versions through 3.1.0
• WordPress installations with the affected plugin versions
• WooCommerce stores utilizing bKash payment integration

Technical Details for CVE-2025-62754

Vulnerability Analysis

This vulnerability stems from missing authorization checks within the Payment Gateway bKash for WC plugin. The plugin fails to properly validate user permissions before allowing access to sensitive functionality, resulting in a broken access control condition. Attackers can exploit this weakness to access administrative or privileged functions without proper authentication or authorization.

The vulnerability affects the plugin's access control mechanisms, where security level configurations are not properly enforced. This allows unauthenticated or low-privileged users to potentially interact with payment gateway functions that should be restricted to administrators or authorized personnel only.

Root Cause

The root cause of CVE-2025-62754 is the absence of proper authorization checks (CWE-862: Missing Authorization) in the plugin's codebase. The affected versions fail to implement adequate permission verification before executing privileged operations. This design flaw means that security-critical functions can be accessed without verifying whether the requesting user has the appropriate permissions to perform the action.

In WordPress plugins, this typically manifests when AJAX handlers, REST API endpoints, or administrative functions do not include proper current_user_can() capability checks or nonce verification.

Attack Vector

An attacker can exploit this vulnerability by sending crafted requests to the vulnerable plugin endpoints without proper authorization. Since the plugin does not validate user permissions correctly, the attacker can:

1. Access payment gateway configuration settings
2. Potentially manipulate transaction data or payment flows
3. Retrieve sensitive information related to bKash payment processing
4. Perform administrative actions without appropriate privileges

The attack can be executed remotely by any user who can send HTTP requests to the WordPress installation, making this a significant security concern for e-commerce sites using this payment gateway.

Detection Methods for CVE-2025-62754

Indicators of Compromise

• Unexpected access to WooCommerce payment gateway settings by non-administrative users
• Unusual API calls or AJAX requests targeting the woo-payment-bkash plugin endpoints
• Unauthorized modifications to bKash payment configuration
• Anomalous user activity logs showing access to payment-related administrative functions

Detection Strategies

• Monitor WordPress audit logs for unauthorized access attempts to payment gateway settings
• Implement web application firewall (WAF) rules to detect suspicious requests to the affected plugin endpoints
• Review access logs for patterns indicating broken access control exploitation
• Deploy SentinelOne Singularity to detect and respond to suspicious activity on web servers

Monitoring Recommendations

• Enable comprehensive logging for all WooCommerce and payment gateway activities
• Set up alerts for configuration changes to payment gateway settings
• Monitor for unusual patterns in user session behavior related to payment functions
• Regularly audit user capabilities and role assignments in WordPress

How to Mitigate CVE-2025-62754

Immediate Actions Required

• Update the Payment Gateway bKash for WC plugin to a patched version when available
• Temporarily disable the plugin if a patch is not yet available and the site is at risk
• Review and audit all user accounts for unauthorized privilege escalation
• Implement additional access controls at the web server or WAF level

Patch Information

Organizations should monitor the Patchstack Vulnerability Report for updates on remediation and patched versions. The vulnerability affects Payment Gateway bKash for WC versions through 3.1.0. Users should update to the latest version once a security patch is released by the plugin developer.

Workarounds

• Restrict access to WordPress admin and WooCommerce endpoints using IP whitelisting
• Implement additional authentication layers for payment gateway administrative functions
• Use a WordPress security plugin to add capability checks and access logging
• Consider temporarily switching to an alternative payment gateway until the vulnerability is patched

# Configuration example - Restrict access to plugin endpoints via .htaccess
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} ^.*woo-payment-bkash.*$ [NC]
    RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
    RewriteRule ^(.*)$ - [F,L]
</IfModule>
