CVE-2026-41460: SocialEngine SQL Injection Vulnerability

CVE-2026-41460 Overview

SocialEngine versions 7.8.0 and prior contain a critical SQL injection vulnerability in the /activity/index/get-memberall endpoint. User-supplied input passed via the text parameter is not properly sanitized before being incorporated into a SQL query, allowing unauthenticated remote attackers to execute arbitrary SQL commands against the backend database.

Critical Impact

This vulnerability enables unauthenticated attackers to read arbitrary database contents, reset administrator passwords, and potentially achieve remote code execution through the Admin Panel's Packages Manager.

Affected Products

• SocialEngine version 7.8.0
• SocialEngine versions prior to 7.8.0

Technical Details for CVE-2026-41460

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists because user input is directly concatenated into SQL queries without proper sanitization or parameterization. The vulnerable endpoint /activity/index/get-memberall accepts a text parameter that an attacker can manipulate to inject malicious SQL statements.

The lack of input validation allows attackers to bypass application logic entirely and interact directly with the underlying database. Since the endpoint is accessible without authentication, any remote attacker can exploit this vulnerability to extract sensitive information, modify data, or escalate privileges within the application.

Root Cause

The root cause of this vulnerability is improper input validation and the failure to use parameterized queries or prepared statements when handling user-supplied data in the text parameter. The application directly incorporates untrusted input into dynamically constructed SQL queries, creating a classic SQL injection attack surface.

Attack Vector

An attacker can exploit this vulnerability by sending a crafted HTTP request to the /activity/index/get-memberall endpoint with a malicious payload in the text parameter. The attack is network-based and requires no authentication or user interaction.

The exploitation chain can proceed as follows:

1. Data Extraction: The attacker uses UNION-based or blind SQL injection techniques to extract sensitive data including user credentials, personal information, and application configuration details.

2. Administrator Compromise: By querying the users table, attackers can obtain administrator account details and reset passwords to gain administrative access.

3. Remote Code Execution: Once authenticated as an administrator, the attacker can leverage the Packages Manager functionality in the Admin Panel to upload and execute malicious code on the server.

Detection Methods for CVE-2026-41460

Indicators of Compromise

• Unusual HTTP requests to /activity/index/get-memberall containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /*)
• Multiple rapid requests to the vulnerable endpoint from a single source IP
• Database logs showing unexpected queries or error messages related to SQL syntax
• Unauthorized changes to administrator accounts or password reset events
• Unexpected package installations or modifications in the Admin Panel

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in the text parameter
• Monitor access logs for requests to /activity/index/get-memberall with encoded or suspicious payloads
• Enable database query logging and alert on queries containing anomalous patterns or unauthorized data access
• Configure intrusion detection systems to flag network traffic containing common SQL injection signatures targeting SocialEngine installations

Monitoring Recommendations

• Establish baseline traffic patterns for the /activity/index/get-memberall endpoint and alert on deviations
• Implement real-time monitoring of database authentication events and privilege escalation attempts
• Enable audit logging for the Admin Panel, particularly the Packages Manager functionality
• Deploy file integrity monitoring on web server directories to detect unauthorized code uploads

How to Mitigate CVE-2026-41460

Immediate Actions Required

• Restrict access to the /activity/index/get-memberall endpoint using web server configuration or firewall rules
• Implement a web application firewall with SQL injection protection rules
• Review administrator accounts for unauthorized changes and reset credentials if compromise is suspected
• Audit the Packages Manager for any unauthorized installations
• Consider taking affected SocialEngine installations offline until a patch is available

Patch Information

At the time of publication, no official vendor patch has been confirmed. Organizations should monitor the SocialEngine website and the VulnCheck SQL Injection Advisory for updates regarding security fixes.

Workarounds

• Block or restrict access to the /activity/index/get-memberall endpoint at the web server or reverse proxy level
• Implement input validation at the application level to sanitize the text parameter if source code modification is possible
• Deploy a WAF with strict SQL injection detection rules for the affected endpoint
• Limit network access to SocialEngine installations to trusted IP ranges where feasible

# Apache configuration to block access to vulnerable endpoint

    Order deny,allow
    Deny from all
    # Allow from trusted IPs only if needed
    # Allow from 192.168.1.0/24
