CVE-2026-5372: runZero Platform SQL Injection Vulnerability

CVE-2026-5372 Overview

CVE-2026-5372 is a SQL Injection vulnerability affecting the runZero Platform's saved queries functionality. Introduced in version 4.0.260123.0, this flaw allows attackers to inject malicious SQL commands through improperly sanitized input in the saved queries feature. This is classified as CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection').

Critical Impact
An authenticated attacker with high privileges could exploit this vulnerability to execute arbitrary SQL commands, potentially leading to unauthorized access to sensitive data, data modification, or complete database compromise.

Technical Details for CVE-2026-5372

Vulnerability Analysis

This SQL Injection vulnerability exists in the saved queries functionality of the runZero Platform. The application fails to properly neutralize special characters in user-controlled input before constructing SQL queries, allowing an attacker to manipulate database queries. Successful exploitation requires network access, an authenticated user with high privileges, and user interaction, but can result in high impact to confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause is improper input validation and sanitization in the saved queries feature (CWE-89). User-supplied data is concatenated directly into SQL statements without adequate parameterization or escaping, creating an injection point that can be leveraged by attackers to modify query logic or execute additional SQL commands.

Attack Vector

This vulnerability is exploitable over the network. An attacker with high privileges must craft malicious input through the saved queries functionality. The attack requires user interaction and the complexity is considered high due to the specific conditions needed for exploitation. When successfully exploited, the attacker can read or modify database contents and potentially cause denial of service conditions.

The saved queries feature processes user input that is incorporated into backend SQL statements. Without proper input sanitization, specially crafted query parameters can escape the intended SQL context and execute arbitrary database commands. Technical details are available in the runZero Security Advisory.

Detection Methods for CVE-2026-5372

Indicators of Compromise

Unusual SQL syntax patterns in web application logs related to saved queries functionality
Database error messages indicating SQL syntax errors from the runZero Platform
Unexpected database queries or access patterns from the runZero application
Anomalous data access or modification in backend databases

Detection Strategies

Monitor web application logs for SQL injection patterns such as single quotes, UNION statements, or comment sequences in saved query parameters
Implement database activity monitoring to detect unusual query structures originating from the runZero Platform
Deploy web application firewall (WAF) rules to detect and block common SQL injection payloads
Review authentication logs for suspicious high-privilege account activity

Monitoring Recommendations

Enable detailed logging for the runZero Platform saved queries feature
Configure database audit logging to capture all queries executed by the application
Implement alerting for failed database queries that may indicate exploitation attempts
Monitor for privilege escalation attempts within the runZero Platform

How to Mitigate CVE-2026-5372

Immediate Actions Required

Upgrade the runZero Platform to version 4.0.260123.1 or later immediately
Review database logs for signs of previous exploitation attempts
Audit high-privilege user accounts for unauthorized activity
Implement network segmentation to limit access to the runZero Platform

Patch Information

runZero has released version 4.0.260123.1 which addresses this SQL Injection vulnerability. Organizations should apply this update as soon as possible. Detailed release information is available in the runZero Release Notes and the runZero Security Advisory.

Workarounds

Restrict access to the saved queries functionality to only essential personnel until patching is complete
Implement web application firewall rules to filter SQL injection patterns targeting the saved queries endpoint
Review and limit high-privilege account access to reduce the attack surface
Enable enhanced logging and monitoring to detect exploitation attempts

bash

# Verify runZero Platform version after patching
# Ensure version is 4.0.260123.1 or later
runzero --version
