CVE-2026-25022: KiviCare Clinic System SQLi Vulnerability

CVE-2026-25022 Overview

A Blind SQL Injection vulnerability has been discovered in the KiviCare Clinic Management System WordPress plugin developed by Iqonic Design. This vulnerability allows authenticated attackers with low privileges to execute malicious SQL queries against the underlying database, potentially leading to unauthorized data extraction and limited service disruption. The vulnerability stems from improper neutralization of special elements used in SQL commands.

Critical Impact

Authenticated attackers can exploit this Blind SQL Injection flaw to exfiltrate sensitive patient and clinic data from the WordPress database, compromising healthcare information confidentiality.

Affected Products

• KiviCare Clinic Management System plugin versions through 3.6.16
• WordPress installations running vulnerable KiviCare versions
• Healthcare and clinic management websites using the affected plugin

Technical Details for CVE-2026-25022

Vulnerability Analysis

This vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The Blind SQL Injection variant means the attacker cannot see direct query output but can infer database contents through application behavior changes, timing differences, or conditional responses.

The KiviCare Clinic Management System plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows authenticated users with minimal privileges to manipulate database queries and extract sensitive information through inference-based techniques. Given that KiviCare is designed for healthcare environments, the exposed data may include protected health information (PHI), patient records, appointment details, and administrative credentials.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements in the KiviCare plugin codebase. User-controllable input is directly concatenated into SQL queries without proper escaping or sanitization, enabling attackers to inject malicious SQL syntax that alters the intended query logic.

Attack Vector

The attack is network-based and requires authentication with low-level privileges to the WordPress installation. An attacker with a valid user account can craft malicious requests containing SQL injection payloads. Since this is a Blind SQL Injection vulnerability, the attacker uses techniques such as:

• Boolean-based blind injection: Crafting queries that return different responses based on true/false conditions
• Time-based blind injection: Using SQL SLEEP() or similar functions to infer data through response delays
• Error-based inference: Analyzing application behavior differences when queries succeed or fail

The exploitation does not require user interaction beyond the initial authentication, and the scope is changed (S:C), meaning the vulnerability can impact resources beyond the vulnerable component itself—potentially affecting the entire WordPress database and connected systems.

Detection Methods for CVE-2026-25022

Indicators of Compromise

• Unusual database query patterns in WordPress/MySQL logs containing SQL injection signatures
• Abnormal response time variations on KiviCare plugin endpoints indicative of time-based SQL injection
• Failed or malformed SQL queries logged in database error logs
• Unexpected access patterns from authenticated users to KiviCare plugin functionality

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to KiviCare endpoints
• Monitor WordPress access logs for suspicious parameter values containing SQL metacharacters (', ", --, UNION, SELECT, SLEEP)
• Deploy database activity monitoring to identify anomalous query patterns or execution timing
• Enable WordPress plugin audit logging to track unusual KiviCare API calls

Monitoring Recommendations

• Configure alerting for database query errors and exceptions in MySQL/MariaDB logs
• Monitor network traffic for repeated requests with varying payloads to the same KiviCare endpoints
• Implement rate limiting on authenticated plugin endpoints to slow enumeration attempts
• Review user account activity for accounts making unusual numbers of requests to plugin functionality

How to Mitigate CVE-2026-25022

Immediate Actions Required

• Update the KiviCare Clinic Management System plugin to a patched version when available from Iqonic Design
• Temporarily disable the KiviCare plugin if it is not critical to operations until a patch is applied
• Implement WAF rules to block common SQL injection patterns targeting the plugin
• Audit database access logs for any signs of prior exploitation
• Review and restrict user account privileges to minimize the attack surface

Patch Information

No official patch information is available at the time of publication. Monitor the Patchstack Vulnerability Analysis for updates on remediation guidance and plugin updates from Iqonic Design. Organizations should check the WordPress plugin repository for versions newer than 3.6.16 that address this vulnerability.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules in front of the WordPress installation
• Restrict access to the KiviCare plugin functionality to only trusted administrative users
• Implement network-level access controls to limit who can authenticate to the WordPress instance
• Consider using WordPress security plugins that provide additional input sanitization layers
• Regularly backup the database to enable recovery in case of data compromise

# Example WAF rule configuration for ModSecurity to block SQL injection attempts
# Add to WordPress .htaccess or Apache configuration
