Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the Neo4jChatAgent component of the Langroid framework allows attackers to execute arbitrary commands and access sensitive data within graph databases. This occurs because user-influenced prompts are directly translated into database queries without proper validation, potentially leading to the compromise of all graph data and system-level access if specific server configurations are enabled.
- LLM agent can be tricked to run dangerous commands.
- This could expose or destroy all graph database information.
- Confirm if your LLM applications use this component.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this by influencing the input provided to a Langroid application's Neo4jChatAgent. Because the agent passes language model-generated Cypher queries directly to the Neo4j driver without proper checks, an attacker can craft malicious queries. If the application has specific Neo4j features enabled, this could lead to unauthorized access or destruction of graph data, and potentially system-level compromise.
- Network access required.
- LLM-generated queries trigger vulnerability.
- Risk of data loss and command execution.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, an attacker could leverage prompt injection to manipulate an agent into executing arbitrary Cypher queries against a Neo4j database. This could lead to unauthorized access, modification, or deletion of graph data. If specific server configurations are enabled, an attacker may also gain operating system command and file system access.
- Graph data and sensitive information.
- Via prompt injection and unvalidated queries.
- Data loss or unauthorized system access.
Operational Fix
Recommended remediation, mitigation, and detection steps
The application owner is primarily responsible for this vulnerability, as it resides within the Langroid framework's agent logic. The first step is to identify all instances of Langroid, determine their exposure and criticality, and then work with the vendor-management team to coordinate remediation.
- Application owners must address this.
- Verify Neo4jChatAgent configurations first.
- Plan remediation with vendor coordination.
