CVE-2025-27302: CHATLIVE SQL Injection Vulnerability

CVE-2025-27302 Overview

CVE-2025-27302 is a critical SQL Injection vulnerability affecting the CHATLIVE WordPress plugin developed by Claudio Adrian Marrero. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing unauthenticated attackers to inject malicious SQL queries through the plugin's input handling mechanisms.

Critical Impact

This SQL Injection vulnerability allows unauthenticated attackers to extract sensitive data from WordPress databases, potentially compromising user credentials, personal information, and other confidential data stored within affected installations.

Affected Products

• CHATLIVE WordPress Plugin versions up to and including 2.0.1
• All WordPress installations running vulnerable CHATLIVE versions
• Any web applications integrating the affected CHATLIVE plugin components

Technical Details for CVE-2025-27302

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists within the CHATLIVE WordPress plugin due to inadequate input sanitization. The vulnerability allows attackers to manipulate SQL queries executed by the plugin, potentially leading to unauthorized data access, data modification, or database corruption.

The network-accessible nature of WordPress plugins combined with the lack of authentication requirements makes this vulnerability particularly dangerous. Attackers can exploit this flaw remotely without any prior access to the target system. The scope change indicator suggests that successful exploitation could impact resources beyond the vulnerable component itself, potentially affecting the entire WordPress installation and its underlying database.

The primary impact is unauthorized read access to confidential data stored in the database, with secondary concerns including potential service availability issues due to malicious query execution.

Root Cause

The root cause of CVE-2025-27302 is the failure to properly sanitize user-supplied input before incorporating it into SQL queries. The CHATLIVE plugin does not adequately escape or parameterize database queries, allowing specially crafted input to break out of the intended query structure and execute arbitrary SQL commands.

WordPress provides built-in functions such as $wpdb->prepare() for parameterized queries, but the vulnerable code paths in CHATLIVE appear to bypass these protective measures, directly concatenating user input into SQL statements.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable endpoints within the CHATLIVE plugin.

Typical exploitation involves injecting SQL syntax through form fields, URL parameters, or other input vectors processed by the plugin. The injected payloads can include UNION-based attacks to extract data from other tables, boolean-based blind injection for data enumeration, or time-based techniques for inferring database contents when direct output is not available.

For detailed technical information about this vulnerability, refer to the Patchstack security advisory.

Detection Methods for CVE-2025-27302

Indicators of Compromise

• Unusual or malformed HTTP requests to CHATLIVE plugin endpoints containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Database error messages appearing in web server logs or application responses
• Unexplained database queries with UNION SELECT, OR 1=1, or other SQL injection patterns in database logs
• Evidence of bulk data extraction or unusual database read activity

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress plugins
• Monitor web server access logs for requests containing SQL injection signatures directed at /wp-content/plugins/chatlive/ paths
• Enable WordPress debug logging to capture database query errors that may indicate exploitation attempts
• Deploy database activity monitoring to identify anomalous query patterns or unauthorized data access

Monitoring Recommendations

• Configure real-time alerting for SQL injection attack patterns in WAF or IDS/IPS systems
• Review database query logs regularly for suspicious activity originating from the CHATLIVE plugin
• Monitor for new or modified database users that could indicate post-exploitation activity
• Track outbound data transfers that may indicate successful data exfiltration

How to Mitigate CVE-2025-27302

Immediate Actions Required

• Deactivate and remove the CHATLIVE plugin immediately if running version 2.0.1 or earlier
• Review database logs and web server access logs for evidence of exploitation attempts
• Consider resetting database credentials and WordPress administrator passwords as a precautionary measure
• Conduct a security audit of the WordPress installation to identify any signs of compromise

Patch Information

As of the publication date, no patched version has been confirmed. Users should check the Patchstack advisory for updates regarding security fixes. Until a patch is available, complete removal of the plugin is the recommended course of action.

Organizations relying on live chat functionality should evaluate alternative WordPress plugins with better security track records and active maintenance.

Workarounds

• Completely disable or uninstall the CHATLIVE plugin until a security patch is released
• Implement WAF rules to filter requests containing SQL injection payloads targeting CHATLIVE endpoints
• Restrict access to WordPress administrative and plugin directories using .htaccess rules or server-level access controls
• Apply the principle of least privilege to database accounts used by WordPress, limiting permissions to only what is necessary

# Example: Block access to CHATLIVE plugin directory via .htaccess
# Add to WordPress root .htaccess file

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^wp-content/plugins/chatlive/ - [F,L]
</IfModule>

# Alternatively, restrict database user privileges
# Run in MySQL/MariaDB console:
# REVOKE ALL PRIVILEGES ON wordpress_db.* FROM 'wp_user'@'localhost';
# GRANT SELECT, INSERT, UPDATE, DELETE ON wordpress_db.* TO 'wp_user'@'localhost';
