CVE-2025-69366: Emerce Core Blind SQL Injection Flaw

CVE-2025-69366 Overview

CVE-2025-69366 is a critical SQL Injection vulnerability discovered in the TeconceTheme Emerce Core (emerce-core) WordPress plugin. The vulnerability allows unauthenticated attackers to perform Blind SQL Injection attacks against affected WordPress installations, potentially compromising the confidentiality of the database and causing service disruption.

Critical Impact

This Blind SQL Injection vulnerability enables attackers to extract sensitive data from WordPress databases without authentication, potentially exposing user credentials, personal information, and other confidential data stored in affected systems.

Affected Products

• TeconceTheme Emerce Core plugin versions through 1.8
• WordPress installations using vulnerable versions of emerce-core

Technical Details for CVE-2025-69366

Vulnerability Analysis

This vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89). The Emerce Core plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating an opportunity for attackers to inject malicious SQL statements. The blind nature of this injection means attackers cannot directly view query results but can infer information through application behavior differences, timing delays, or error conditions.

The network-accessible attack vector with no authentication requirements significantly increases the risk, as any internet-connected WordPress site running the vulnerable plugin is potentially exposed. Successful exploitation could lead to complete database compromise, enabling attackers to access stored credentials, customer data, and administrative information.

Root Cause

The root cause of CVE-2025-69366 is inadequate input validation and sanitization within the Emerce Core plugin. User-controllable input is directly concatenated or interpolated into SQL queries without proper parameterization or escaping. WordPress provides secure APIs such as $wpdb->prepare() for parameterized queries, but the vulnerable code paths in Emerce Core fail to utilize these protective mechanisms.

Attack Vector

The vulnerability is exploitable remotely over the network without requiring any user interaction or authentication. Attackers can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable plugin endpoints. Through Boolean-based or time-based blind SQL injection techniques, attackers can systematically extract database contents character by character.

Typical attack patterns include:

• Injecting conditional statements to determine database structure through response variations
• Using time-delay functions like SLEEP() to confirm successful injection and extract data
• Leveraging error-based techniques if verbose error messages are enabled

Since no verified code examples are available for this vulnerability, refer to the Patchstack WordPress Vulnerability Advisory for detailed technical information about the vulnerable code paths and exploitation mechanics.

Detection Methods for CVE-2025-69366

Indicators of Compromise

• Unusual SQL error messages in WordPress or web server logs
• Requests containing SQL syntax characters such as single quotes, UNION, SELECT, SLEEP(), or BENCHMARK() functions in query parameters
• Abnormally long response times for specific plugin endpoints suggesting time-based injection attempts
• Database query logs showing unexpected or malformed queries originating from the emerce-core plugin

Detection Strategies

• Deploy Web Application Firewalls (WAF) with SQL injection detection rules to block malicious requests targeting WordPress installations
• Enable and monitor WordPress debug logging to capture suspicious database query activity
• Implement intrusion detection signatures for common Blind SQL Injection patterns including time-based payloads
• Use SentinelOne's WordPress plugin inventory scanning to identify vulnerable emerce-core installations across your environment

Monitoring Recommendations

• Monitor web server access logs for requests containing encoded SQL injection payloads targeting emerce-core endpoints
• Set up alerts for unusual database query execution times that may indicate time-based extraction attempts
• Track failed authentication attempts and suspicious data access patterns that could indicate post-exploitation activity

How to Mitigate CVE-2025-69366

Immediate Actions Required

• Immediately update the Emerce Core plugin to a version newer than 1.8 if a patched version is available from the vendor
• If no patch is available, consider temporarily deactivating the emerce-core plugin until a security update is released
• Implement WAF rules to filter SQL injection attempts targeting the affected plugin
• Review database access logs for signs of prior exploitation attempts

Patch Information

Consult the Patchstack WordPress Vulnerability Advisory for the latest patching guidance and update information from the vendor. Ensure your WordPress installation is configured to receive plugin security updates promptly.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection enabled as a defensive layer
• Restrict access to WordPress admin and plugin endpoints using IP allowlisting where feasible
• Disable the emerce-core plugin entirely if it is not critical to site functionality until a patch is available
• Implement database user permission restrictions to limit the impact of potential SQL injection attacks

# WordPress CLI command to deactivate the vulnerable plugin
