CVE-2025-32303: WPCHURCH SQL Injection Vulnerability

CVE-2025-32303 Overview

CVE-2025-32303 is a critical SQL Injection vulnerability affecting the Mojoomla WPCHURCH WordPress plugin. The vulnerability allows unauthenticated attackers to perform Blind SQL Injection attacks against WordPress sites running vulnerable versions of the plugin. Due to improper neutralization of special elements used in SQL commands (CWE-89), malicious actors can manipulate database queries to extract sensitive information or potentially compromise the underlying database.

Critical Impact

Unauthenticated attackers can exploit this Blind SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, personally identifiable information, and other confidential data stored by the church management plugin.

Affected Products

• Mojoomla WPCHURCH plugin versions up to and including 2.7.0
• WordPress installations running the vulnerable WPCHURCH (church-management) plugin
• All WordPress sites with WPCHURCH plugin installed without security patches

Technical Details for CVE-2025-32303

Vulnerability Analysis

This SQL Injection vulnerability exists due to inadequate input validation and sanitization within the WPCHURCH WordPress plugin. The plugin fails to properly neutralize user-supplied input before incorporating it into SQL queries, allowing attackers to inject malicious SQL code that is executed by the database backend.

The Blind SQL Injection variant present in this vulnerability means that attackers cannot directly see the results of their injected queries in the application's response. Instead, they must infer information by observing differences in application behavior, response times, or error conditions. This technique allows attackers to methodically extract data character by character or leverage time-based inference techniques to confirm successful query execution.

Given the network-accessible attack vector with no authentication required, any WordPress site running the vulnerable WPCHURCH plugin is potentially at risk. The vulnerability can lead to significant confidentiality breaches, as attackers can extract sensitive church member data, administrative credentials, and other confidential information stored in the WordPress database.

Root Cause

The root cause of this vulnerability is improper neutralization of special elements used in SQL commands (CWE-89). The WPCHURCH plugin fails to implement proper parameterized queries or adequate input sanitization for user-controlled data before including it in SQL statements. This allows special SQL characters and syntax to be interpreted as part of the database query rather than as literal data values.

WordPress plugins that handle form inputs, URL parameters, or other user-supplied data must properly escape and sanitize all inputs using WordPress's built-in database abstraction layer ($wpdb->prepare()) to prevent SQL injection attacks.

Attack Vector

The attack vector for CVE-2025-32303 is network-based, requiring no authentication or user interaction. An attacker can remotely target vulnerable WordPress installations by submitting specially crafted requests containing malicious SQL payloads. The Blind SQL Injection technique involves:

1. Identifying injectable parameters within the WPCHURCH plugin
2. Crafting payloads that cause detectable changes in application behavior or response timing
3. Using boolean-based or time-based inference to extract data from the database
4. Iteratively querying the database to retrieve sensitive information such as usernames, password hashes, and plugin configuration data

Since the vulnerability affects a church management plugin, attackers may specifically target congregation member data, donation records, and administrative access credentials. For detailed technical information, refer to the Patchstack security advisory.

Detection Methods for CVE-2025-32303

Indicators of Compromise

• Unusual or malformed HTTP requests targeting WPCHURCH plugin endpoints containing SQL syntax characters (e.g., ', ", --, UNION, SELECT, WAITFOR, SLEEP)
• Database query logs showing unexpected queries with time delays or conditional logic patterns
• Increased database load or response latency indicative of time-based SQL injection probing
• Web server access logs containing encoded SQL payloads in request parameters

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in requests to WordPress installations
• Enable WordPress database query logging and monitor for anomalous query patterns or syntax
• Implement intrusion detection system (IDS) signatures for SQL injection attack patterns targeting WordPress plugins
• Review web server access logs for requests containing SQL metacharacters directed at WPCHURCH plugin URLs

Monitoring Recommendations

• Monitor database performance metrics for unusual spikes in query execution time that may indicate time-based blind SQL injection attempts
• Configure alerting for repeated failed or malformed requests to WordPress plugin endpoints
• Implement real-time log analysis to detect SQL injection attack signatures across all WordPress installations in your environment
• Regularly audit installed WordPress plugins against known vulnerability databases such as Patchstack

How to Mitigate CVE-2025-32303

Immediate Actions Required

• Identify all WordPress installations running the WPCHURCH plugin and determine the installed version
• If running version 2.7.0 or earlier, immediately assess the risk and consider disabling the plugin until a patch is available
• Implement WAF rules to block SQL injection attempts targeting the vulnerable plugin
• Review database and web server logs for evidence of exploitation attempts

Patch Information

At the time of publication, organizations should check the Patchstack advisory for the latest patch availability and update the WPCHURCH plugin to the most recent secure version as soon as a fix is released by Mojoomla. Always verify plugin updates are from official WordPress plugin repository sources.

Workarounds

• Temporarily disable the WPCHURCH plugin if it is not business-critical until a security patch is available
• Implement Web Application Firewall rules to filter and block SQL injection attack patterns targeting the plugin
• Restrict access to WordPress administrative functions and plugin endpoints using IP allowlisting where feasible
• Consider database user privilege reduction to limit the potential impact of SQL injection attacks

# Example WAF rule configuration (ModSecurity)
# Add SQL injection protection for WordPress plugins
SecRule REQUEST_URI "@contains /wp-content/plugins/church-management/" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\

    SecRule ARGS "@detectSQLi" \
