Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a vulnerability in Flowise, a tool used for building custom large language model workflows, that could allow an authenticated attacker to execute arbitrary code. The issue stems from how the SQLite Record Manager node handles configuration, potentially enabling an attacker to overwrite critical database paths and inject malicious commands.
- Code execution risk in LLM workflow builder.
- Confirms exposure and relevance for leadership.
- Assess impact and review relevant deployments.
Attack Path
How an attacker could exploit the issue
An authenticated attacker with access to Flowise could manipulate the SQLite Record Manager node. By providing malicious input in the `additionalConfig.database` field, the attacker can overwrite the database path. This allows them to write a SQLite database to sensitive system locations, which, when leveraged by Puppeteer launching Chromium, can lead to arbitrary command execution.
- Authenticated access required.
- Control database path and content.
- Arbitrary command execution.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, an authenticated attacker could potentially overwrite critical system configuration files by manipulating the SQLite Record Manager node. This could lead to arbitrary code execution when a component within the application launches Chromium.
- System configuration files could be affected.
- Attacker could inject shell syntax.
- Arbitrary code execution may occur.
Operational Fix
Recommended remediation, mitigation, and detection steps
Given Flowise's nature as a drag-and-drop interface for LLM flows, likely deployed as a web application, the teams responsible for its security would typically include application owners and potentially platform or infrastructure teams managing the hosting environment. The initial step is to identify all instances of Flowise, assess their reachability and business criticality, pinpoint the accountable owners, and then prioritize remediation efforts based on the identified risks.
- Identify Flowise instances; confirm owners.
- Verify external exposure and criticality.
- Plan remediation based on risk.
