CVE-2026-26001 Overview
CVE-2026-26001 is an SQL Injection vulnerability affecting the GLPI Inventory Plugin, which is responsible for network discovery, inventory management, software deployment, and data collection for GLPI agents. The vulnerability stems from improper sanitization of user input in the reports functionality, allowing authenticated attackers with adequate privileges to execute arbitrary SQL commands against the backend database.
Critical Impact
Authenticated attackers can exploit unsanitized input in the reports feature to perform SQL injection attacks, potentially leading to unauthorized data access and database manipulation.
Affected Products
- GLPI Inventory Plugin versions prior to 1.6.6

Technical Details for CVE-2026-26001
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) exists in the GLPI Inventory Plugin's reports functionality. The flaw occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterization. An authenticated attacker with adequate reporting privileges can craft malicious input that modifies the intended SQL query logic, enabling unauthorized database operations.
The attack requires network access and valid authentication credentials with sufficient privileges to access the reporting feature. While this reduces the attack surface compared to unauthenticated vulnerabilities, the potential impact remains significant as successful exploitation could expose sensitive inventory data, network discovery information, and other confidential details stored in the GLPI database.
Root Cause
The root cause of this vulnerability is improper input validation and the lack of parameterized queries in the reports module. User-controlled input is directly concatenated into SQL query strings instead of being properly escaped or bound as parameters, creating a classic SQL injection attack surface.
Attack Vector
The attack is network-based and requires an authenticated session with appropriate privileges to access the reports functionality. An attacker can inject malicious SQL syntax through report parameters, potentially allowing them to:
- Extract sensitive data from the database
- Modify or delete database records
- Bypass authorization controls
- Enumerate database schema and structure
The vulnerability manifests in the reports processing logic where user input is not adequately sanitized before being used in database queries. For technical details and specific affected code paths, refer to the GitHub Security Advisory.
Detection Methods for CVE-2026-26001
Indicators of Compromise
- Unusual or malformed SQL syntax appearing in web server access logs related to GLPI report endpoints
- Database error messages or exceptions triggered by malformed queries in application logs
- Unexpected database queries containing UNION, SELECT, INSERT, UPDATE, or DELETE statements from the reports feature
- Anomalous data access patterns or bulk data extraction from the GLPI database
Detection Strategies
- Monitor web application firewall (WAF) logs for SQL injection patterns targeting GLPI endpoints
- Implement database activity monitoring to detect anomalous query patterns from the GLPI application
- Review GLPI application logs for error messages indicating SQL syntax errors or unexpected query behavior
- Deploy intrusion detection signatures that identify common SQL injection payloads in HTTP requests
Monitoring Recommendations
- Enable detailed logging on the GLPI web server and database server to capture suspicious activity
- Configure alerting for database errors originating from the GLPI Inventory Plugin reports module
- Monitor for unusual authentication patterns or privilege escalation attempts in GLPI
- Implement real-time log analysis to correlate potential exploitation attempts across web and database tiers
How to Mitigate CVE-2026-26001
Immediate Actions Required
- Upgrade the GLPI Inventory Plugin to version 1.6.6 or later immediately
- Review access controls and limit reporting privileges to essential personnel only
- Audit recent report activity logs for signs of exploitation
- Consider temporarily disabling the reports feature if immediate patching is not possible
Patch Information
The vulnerability has been addressed in GLPI Inventory Plugin version 1.6.6. Organizations should upgrade to this version or later to remediate the SQL injection vulnerability. The fix implements proper input sanitization and parameterized queries in the reports functionality.
For detailed patch information, refer to the GitHub Security Advisory.
Workarounds
- Restrict access to the reports functionality to trusted administrators only until patching is complete
- Implement a web application firewall (WAF) with SQL injection detection rules as a temporary mitigation layer
- Monitor and audit all report-related database queries for suspicious patterns
- Consider network segmentation to limit database access from untrusted network segments
# Verify GLPI Inventory Plugin version
# Check the plugin version in GLPI administration panel
# Navigate to: Setup > Plugins > GLPI Inventory
# Ensure version is 1.6.6 or higher
# Alternative: Check version file directly
