We do not accept AI generated security reports. We receive a large number of these and we absolutely do not have the resources to review them all. If you submit one that will be an automatic ban from the project.
Kilo CLI is an AI-powered coding assistant that runs locally on your machine. It provides an agent system with access to powerful tools including shell execution, file operations, and web access.
Kilo CLI does not sandbox the agent. The permission system exists as a UX feature to help users stay aware of what actions the agent is taking - it prompts for confirmation before executing commands, writing files, etc. However, it is not designed to provide security isolation.
If you need true isolation, run Kilo CLI inside a Docker container or VM.
Server mode is opt-in only. When enabled, set KILO_SERVER_PASSWORD to require HTTP Basic Auth. Without this, the server runs unauthenticated (with a warning). It is the end user's responsibility to secure the server - any functionality it provides is not a vulnerability.
| Category | Rationale |
|---|---|
| Server access when opted-in | If you enable server mode, API access is expected behavior |
| Sandbox escapes | The permission system is not a sandbox (see above) |
| LLM provider data handling | Data sent to your configured LLM provider is governed by their policies |
| MCP server behavior | External MCP servers you configure are outside our trust boundary |
| Malicious config files | Users control their own config; modifying it is not an attack vector |
We value the contributions of the security research community and recognize the importance of a coordinated approach to vulnerability disclosure. If you have discovered a security vulnerability, we encourage you to let us know immediately. We welcome the opportunity to work with you to resolve the issue promptly.
Please email your findings to security@kilo.ai. We will acknowledge your report and work with you to resolve the issue.
After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.
