Horizon Alert
Summary of the vulnerability and why it matters
This critical vulnerability in Flowise allows for unauthenticated remote command execution. Attackers can exploit a parameter override bypass to run arbitrary system commands with root privileges within the Flowise container.
- No authentication needed
- Requires single HTTP request
- Root privileges gained
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending a crafted HTTP request to an unauthenticated Flowise instance. This request manipulates parameters to inject commands, allowing arbitrary code execution with root privileges within the container.
- No authentication required
- Target Flowise web interface
- Requires specific parameter injection
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in Flowise presents a clear path for attackers to execute arbitrary commands with root privileges remotely and without authentication. The ease of exploitation, combined with the critical nature of the vulnerability, suggests a high likelihood of weaponization by threat actors targeting environments using affected versions. While the tool may often be used internally, its network accessibility and the severity of the flaw make it an attractive target.
- Exploitable via HTTP request.
- No authentication required.
- Critical command execution.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize patching or upgrading Flowise instances to version 3.1.0 or later immediately due to the critical unauthenticated remote command execution vulnerability. If immediate patching is not feasible, isolate affected services from the network or restrict access to prevent exploitation.
- Upgrade Flowise to 3.1.0+.
- Isolate affected services from network.
- Monitor for suspicious outbound connections.
