CVE-2026-24624: Neoforum SQL Injection Vulnerability

CVE-2026-24624 Overview

CVE-2026-24624 is a SQL Injection vulnerability affecting the Neoforum WordPress plugin developed by saeros1984. The vulnerability allows attackers to perform Blind SQL Injection attacks against vulnerable installations. This type of vulnerability occurs when user-supplied input is not properly sanitized before being included in SQL queries, enabling attackers to manipulate database operations and potentially extract sensitive data.

Critical Impact

Successful exploitation of this Blind SQL Injection vulnerability could allow attackers with high privileges to extract, modify, or delete sensitive database information, compromising the confidentiality, integrity, and availability of the affected WordPress installation.

Affected Products

• Neoforum WordPress Plugin version 1.0 and earlier
• WordPress installations running vulnerable Neoforum plugin versions

Technical Details for CVE-2026-24624

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The Neoforum plugin fails to properly sanitize user input before incorporating it into SQL queries, creating an attack surface for Blind SQL Injection. In a Blind SQL Injection scenario, the attacker cannot directly see the results of their queries but can infer information based on the application's behavior, response times, or error conditions.

The vulnerability requires authentication with high-level privileges to exploit, which provides some mitigation against opportunistic attacks. However, once exploited, attackers can achieve complete compromise of database confidentiality, integrity, and availability.

Root Cause

The root cause of this vulnerability lies in the improper input validation and sanitization within the Neoforum plugin. User-controlled input is directly concatenated into SQL queries without using prepared statements or parameterized queries, which are standard defenses against SQL Injection attacks. This implementation flaw allows specially crafted input to break out of the intended query context and inject malicious SQL commands.

Attack Vector

The attack is network-based and does not require user interaction. An authenticated attacker with elevated privileges can send specially crafted HTTP requests to the vulnerable WordPress installation. The malicious payload is processed by the Neoforum plugin and executed against the database. Due to the blind nature of this injection, attackers typically use time-based or boolean-based inference techniques to extract data character by character.

The vulnerability is documented in the Patchstack WordPress Vulnerability Database, which provides additional context on the affected plugin and vulnerability details.

Detection Methods for CVE-2026-24624

Indicators of Compromise

• Unusual database query patterns or errors in WordPress/database logs
• Slow database response times indicating time-based SQL injection attempts
• Suspicious requests containing SQL syntax characters such as single quotes, UNION statements, or SLEEP commands targeting Neoforum plugin endpoints
• Unexpected data modifications or exfiltration from the WordPress database

Detection Strategies

• Monitor web application firewall (WAF) logs for SQL injection patterns targeting WordPress plugins
• Implement database activity monitoring to detect unusual query structures or timing anomalies
• Review access logs for repeated requests with varying payloads to Neoforum-related URLs
• Deploy intrusion detection rules specifically targeting Blind SQL Injection techniques

Monitoring Recommendations

• Enable verbose logging on WordPress and the underlying database to capture suspicious query activity
• Configure alerting for database queries with abnormal execution times that may indicate time-based injection
• Regularly audit privileged user accounts and their activities within the WordPress admin interface
• Implement real-time monitoring for changes to sensitive database tables

How to Mitigate CVE-2026-24624

Immediate Actions Required

• Deactivate and remove the Neoforum plugin from all WordPress installations until a patched version is available
• Audit database logs for signs of previous exploitation attempts
• Review and restrict administrative privileges to minimize the attack surface
• Implement a Web Application Firewall (WAF) with SQL injection detection rules as an additional layer of protection

Patch Information

As of the last modification date (2026-01-26), there is no confirmed vendor patch available for this vulnerability. The issue affects Neoforum version 1.0 and all prior versions. Site administrators should monitor the plugin's official repository and the Patchstack advisory for updates on patch availability.

Workarounds

• Disable the Neoforum plugin entirely until a security patch is released
• Implement input validation and output encoding at the application layer using security plugins
• Deploy a WAF configured to block SQL injection attempts targeting WordPress plugins
• Restrict access to the WordPress admin area using IP allowlisting or additional authentication mechanisms
• Consider migrating to an alternative, actively maintained forum plugin with a better security track record
