CVE-2025-54048: miniOrange Custom API SQLi Vulnerability

CVE-2025-54048 Overview

CVE-2025-54048 is a critical SQL Injection vulnerability affecting the miniOrange Custom API for WP WordPress plugin. This vulnerability allows unauthenticated attackers to inject malicious SQL commands through specially crafted input, potentially compromising the entire WordPress database. The flaw stems from improper neutralization of special elements used in SQL commands (CWE-89).

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, personal information, and potentially gain complete control over the affected WordPress installation.

Affected Products

• miniOrange Custom API for WP versions through 4.2.2
• WordPress installations using the vulnerable plugin versions

Technical Details for CVE-2025-54048

Vulnerability Analysis

This SQL Injection vulnerability exists in the miniOrange Custom API for WP plugin, which is used to create custom REST API endpoints for WordPress sites. The vulnerability allows attackers to manipulate database queries by injecting malicious SQL statements through user-controllable input fields. Since the vulnerability requires no authentication and can be exploited remotely over the network, it poses a significant risk to affected WordPress installations. The attack can result in unauthorized access to sensitive database contents and may cause limited service disruption.

Root Cause

The root cause of CVE-2025-54048 is the failure to properly sanitize and validate user-supplied input before incorporating it into SQL queries. The plugin does not adequately escape or parameterize special SQL characters and keywords, allowing attackers to break out of the intended query structure and execute arbitrary SQL commands against the WordPress database.

Attack Vector

The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting the vulnerable API endpoints exposed by the Custom API for WP plugin. These payloads can be designed to extract data from the database using techniques such as UNION-based injection, blind SQL injection, or error-based injection methods.

The attack typically involves sending specially crafted parameters through the custom API endpoints that the plugin creates. When these malicious inputs reach the database layer without proper sanitization, the injected SQL commands execute with the privileges of the WordPress database user.

Detection Methods for CVE-2025-54048

Indicators of Compromise

• Unusual database queries in MySQL/MariaDB logs containing SQL injection patterns such as UNION SELECT, OR 1=1, or encoded SQL keywords
• Anomalous API requests to Custom API for WP endpoints with suspicious parameter values
• Unexpected database access patterns or data exfiltration attempts
• Error messages in server logs indicating SQL syntax errors from malformed injection attempts

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests
• Monitor WordPress access logs for requests containing SQL injection signatures targeting /wp-json/ or custom API endpoints
• Implement database activity monitoring to detect unauthorized query patterns
• Review plugin-specific endpoints for unusual request volumes or parameter lengths

Monitoring Recommendations

• Enable detailed logging on the WordPress database to capture all queries from the vulnerable plugin
• Configure real-time alerting for detected SQL injection attempts
• Monitor for bulk data extraction patterns that may indicate successful exploitation
• Track changes to WordPress user accounts, especially privilege escalations

How to Mitigate CVE-2025-54048

Immediate Actions Required

• Update the miniOrange Custom API for WP plugin to a patched version immediately if available
• If no patch is available, consider temporarily disabling the plugin until a fix is released
• Implement WAF rules to block SQL injection attempts targeting the vulnerable endpoints
• Review database access logs for signs of prior exploitation
• Audit WordPress user accounts for any unauthorized changes

Patch Information

Security advisory and vulnerability details are available through Patchstack's vulnerability database. WordPress administrators should check for plugin updates through the WordPress dashboard or the official WordPress plugin repository for the latest patched version of Custom API for WP.

Workarounds

• Temporarily disable the Custom API for WP plugin if it is not essential to site operations
• Implement a Web Application Firewall with SQL injection detection rules
• Restrict access to WordPress REST API endpoints using .htaccess or server configuration
• Apply the principle of least privilege to the WordPress database user account to limit potential damage from exploitation

# Example: Block suspicious requests via .htaccess
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} [^a-z](union|select|insert|drop|delete|update|concat|load_file)[^a-z] [NC]
    RewriteRule .* - [F,L]
</IfModule>
