CVE-2026-5596: Griptape-AI Griptape SQL Injection Flaw

CVE-2026-5596 Overview

A SQL injection vulnerability was discovered in the griptape-ai griptape framework version 0.19.4. The vulnerability exists within the griptape/tools/sql/tool.py file of the SqlTool component. Due to insufficient input validation, an attacker can remotely manipulate SQL queries, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed, and the vendor was contacted but did not respond to the disclosure.

Critical Impact

This SQL injection vulnerability allows remote attackers to manipulate database queries through the SqlTool component, potentially compromising data integrity and confidentiality in AI applications using the griptape framework.

Affected Products

• griptape-ai griptape version 0.19.4
• Applications utilizing the SqlTool component from the affected version

Technical Details for CVE-2026-5596

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as injection vulnerabilities. The SqlTool component in griptape fails to properly sanitize user-controlled input before incorporating it into SQL queries. This allows attackers to inject malicious SQL code that gets executed against the backend database.

The griptape framework is designed for building AI applications, and the SqlTool provides database interaction capabilities. When user input is passed through AI agents to the SqlTool without proper parameterization or escaping, the injected SQL commands execute with the same privileges as the application's database connection.

Root Cause

The root cause lies in the improper handling of user-supplied input within the griptape/tools/sql/tool.py file. The SqlTool component does not implement adequate input sanitization or parameterized queries, allowing raw user input to be concatenated directly into SQL statements. This classic SQL injection pattern enables attackers to break out of the intended query structure and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network. An attacker with low privileges can craft malicious input that, when processed by an AI application using the vulnerable SqlTool, results in SQL injection. The attack requires no user interaction and can affect the confidentiality, integrity, and availability of the database being accessed by the application.

The exploitation path involves:

1. Identifying an AI application using the vulnerable griptape SqlTool
2. Crafting input containing SQL injection payloads
3. Submitting the malicious input through the application's interface
4. The SqlTool processes the input without sanitization, executing the injected SQL

Detailed technical information about this vulnerability can be found in the GitHub Issue on CVE Tool and the VulDB Vulnerability entry.

Detection Methods for CVE-2026-5596

Indicators of Compromise

• Unusual database query patterns containing SQL syntax characters (single quotes, semicolons, UNION statements)
• Unexpected database errors in application logs indicating malformed queries
• Database audit logs showing unauthorized data access or modifications
• Network traffic containing SQL injection payloads targeting the griptape application

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect common SQL injection patterns in requests
• Enable database query logging and monitor for anomalous query structures
• Deploy application-level logging to capture input passed to the SqlTool component
• Use runtime application self-protection (RASP) solutions to detect injection attempts

Monitoring Recommendations

• Monitor database audit logs for queries containing suspicious patterns like OR 1=1, UNION SELECT, or comment sequences
• Set up alerts for database errors that may indicate failed injection attempts
• Track application dependencies and alert when griptape version 0.19.4 is deployed
• Implement anomaly detection for database query frequency and patterns

How to Mitigate CVE-2026-5596

Immediate Actions Required

• Audit all applications using griptape version 0.19.4 with the SqlTool component
• Implement input validation and sanitization at the application layer before data reaches the SqlTool
• Consider disabling or restricting access to the SqlTool component until a patch is available
• Apply network-level restrictions to limit access to affected applications

Patch Information

At the time of publication, no official patch has been released by the vendor. The vendor was contacted about this disclosure but did not respond. Monitor the griptape-ai GitHub repository for security updates. Users should consider upgrading to newer versions when available and verify that the SQL injection vulnerability has been addressed.

Workarounds

• Implement parameterized queries or prepared statements at the application layer when interacting with the SqlTool
• Add a validation layer to sanitize all user input before it reaches the griptape SqlTool
• Use an allowlist approach to restrict the types of SQL operations permitted through the tool
• Deploy a database proxy or firewall to filter potentially malicious queries

# Configuration example - Input validation wrapper for SqlTool
# Add input sanitization before using SqlTool in your application
# Note: This is a defensive measure, not a complete fix

# 1. Restrict database user permissions (principle of least privilege)
# In your database, create a limited user for the application:
# GRANT SELECT ON specific_tables TO 'griptape_app_user'@'localhost';

# 2. Enable query logging for monitoring
# For MySQL/MariaDB:
# SET GLOBAL general_log = 'ON';
# SET GLOBAL general_log_file = '/var/log/mysql/query.log';

# 3. Monitor for SQL injection patterns in logs
grep -E "UNION|SELECT.*FROM|OR.*1.*=.*1|--" /var/log/mysql/query.log
