CVE-2025-48141: Multi CryptoCurrency Payments SQLi Flaw

CVE-2025-48141 Overview

CVE-2025-48141 is a critical SQL Injection vulnerability affecting the Multi CryptoCurrency Payments WordPress plugin developed by Alex Zaytseff. This vulnerability allows unauthenticated attackers to execute arbitrary SQL commands against the underlying database through improper neutralization of special elements used in SQL queries. The vulnerability impacts all versions of the plugin from initial release through version 2.0.3.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, payment information, and cryptocurrency transaction details.

Affected Products

• Multi CryptoCurrency Payments WordPress plugin versions through 2.0.3
• WordPress installations using the vulnerable plugin
• E-commerce sites processing cryptocurrency payments through this plugin

Technical Details for CVE-2025-48141

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists due to improper neutralization of special elements used in SQL commands within the Multi CryptoCurrency Payments plugin. The vulnerability allows attackers to manipulate SQL queries by injecting malicious input that is not properly sanitized before being passed to the database. Given the network-accessible attack vector requiring no authentication or user interaction, attackers can exploit this remotely with minimal complexity. The changed scope indicates the vulnerability can impact resources beyond the vulnerable component itself, potentially compromising the entire WordPress installation and its database contents.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize, escape, or parameterize user-supplied input before incorporating it into SQL queries. The plugin does not implement adequate input validation or use prepared statements with parameterized queries, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely without requiring any authentication or user privileges. The SQL Injection can be triggered by sending specially crafted requests to the vulnerable plugin endpoints. This could allow attackers to:

• Extract sensitive data from the WordPress database including user credentials and payment records
• Modify or delete database records
• Potentially escalate privileges within the WordPress installation
• Access cryptocurrency wallet information and transaction histories stored by the plugin

The vulnerability is particularly concerning given the financial nature of the plugin's functionality, as databases may contain sensitive cryptocurrency payment information.

Detection Methods for CVE-2025-48141

Indicators of Compromise

• Unusual database query patterns in WordPress/MySQL logs containing SQL syntax anomalies
• Unexpected database errors appearing in application logs related to the Multi CryptoCurrency Payments plugin
• Evidence of data exfiltration or unauthorized database access in server logs
• Suspicious HTTP requests to plugin endpoints containing SQL keywords or special characters

Detection Strategies

• Monitor web application firewall (WAF) logs for SQL Injection attempt patterns targeting WordPress plugin endpoints
• Implement database query logging and analyze for anomalous query structures or unauthorized data access
• Deploy intrusion detection rules to identify common SQL Injection payloads in HTTP requests
• Review access logs for requests to the Multi CryptoCurrency Payments plugin with suspicious parameter values

Monitoring Recommendations

• Enable WordPress debug logging to capture plugin-related database errors and anomalies
• Configure database audit logging to track all queries executed by the WordPress application
• Set up alerting for multiple failed database queries or syntax errors that may indicate injection attempts
• Monitor for unusual data access patterns, particularly to user credential or payment-related tables

How to Mitigate CVE-2025-48141

Immediate Actions Required

• Audit WordPress installations for the presence of Multi CryptoCurrency Payments plugin versions 2.0.3 or earlier
• Consider temporarily disabling the plugin until a patched version is available
• Implement Web Application Firewall (WAF) rules to block SQL Injection attempts
• Review database access logs for any evidence of exploitation
• Rotate any credentials that may have been exposed through database access

Patch Information

Security researchers at Patchstack have documented this vulnerability. Users should monitor the plugin's official WordPress repository and the Patchstack vulnerability database for patch availability. Update to a patched version as soon as one is released by the plugin developer.

Workarounds

• Disable the Multi CryptoCurrency Payments plugin until a security patch is available
• Implement WAF rules to filter and block SQL Injection payloads targeting the plugin
• Restrict database user privileges to limit the impact of successful SQL Injection attacks
• Consider using alternative cryptocurrency payment solutions that are not affected by this vulnerability
• Apply network-level access controls to limit exposure of the WordPress installation
