Report privately through GitHub: Security → Report a vulnerability on this repository. That opens a draft advisory only you and the maintainer can read.

Please do not open a public issue for a suspected vulnerability. If GitHub's private reporting is unavailable to you, email the address on the maintainer's commits instead.

A useful report says what an attacker gets, and how to reproduce it. A patch is welcome but never required.

This is a single-maintainer project. Expect an acknowledgement within a week rather than within a day, and no bounty.

Only the latest tagged release. mininaru is pre-1.0 and fixes land on master and in the next tag rather than as backports.

These are bugs. Report them.

• Reaching any /api/v1 endpoint without a valid bearer token, or learning whether a guessed key was close.
• Escaping the working directory from file_read, file_write, or bash_exec — anything that makes the root in modules/file/file.go not hold.
• Running a dangerous tool without the approval gate outside an explicitly trusted directory — a /yolo mode of off (the default) or persist outside its anchor still auto-running a call, or a -p run executing a dangerous tool instead of denying it. This includes prompt injection that defeats the gate, as opposed to injection that merely asks for a tool.
• A provider API key or MININARU_API_KEY appearing in logs, terminal output, an API response, or an error message.
• Any data from one API request surfacing in another. serve is stateless and keeps no conversation between requests, so leakage across them is a bug.

These are documented, deliberate behaviour. A report about them will be closed with a pointer here.

• bash_exec runs shell commands and file_write writes files. That is what the tools are. In the chat client each dangerous call is gated by an approval prompt unless the directory is trusted via /yolo persist/on, and -p denies them outright because nobody is there to approve.
• Provider keys are stored unencrypted in provider.json, written at mode 0600 inside a 0700 data directory. They are masked in list output, not protected at rest. Anyone who can read your home directory can read them.
• Configuring an MCP server runs a program. mcp add --stdio <command> means that command is launched on the next run. Adding one is equivalent to running it yourself.
• A model asking to do something harmful is expected. The approval gate, the permission tiers, and the working-directory root are the controls. Report a way past those, not the request itself.
• Anyone who can write to the data directory controls the agent — its system prompt, its skills, its MCP servers. The directory is the trust boundary.
• serve binds 127.0.0.1 by default and has no TLS. Exposing it with --host 0.0.0.0 puts a bearer token on the wire in plaintext; terminate TLS in front of it.
