+# Security Policy
+
+## Supported versions
+
+| Version | Supported |
+| ------- | --------- |
+| 2.x     | Yes       |
+| 1.x     | No        |
+
+1.x does not build on current Node.js and carries several memory-safety defects that
+2.0.0 fixed, including a fixed-size buffer that arbitrary-length Lua error messages
+were formatted into. Please upgrade rather than asking for a backport.
+
+## Reporting a vulnerability
+
+Please report privately through GitHub's
+[security advisory form](https://github.com/mschmicking/node-lua-runner/security/advisories/new)
+rather than opening a public issue.
+
+Include what you need to reproduce it: the Lua and JavaScript involved, your platform
+and Node.js version, and what you observed.
+
+If that form is not available to you, open an issue asking for a private channel —
+without the details — rather than posting them publicly.
+
+You should get an acknowledgement within a week or so. This is a spare-time project,
+so please treat that as a good-faith aim and not a guarantee.
+
+## Scope
+
+This package embeds a Lua interpreter in your Node.js process, which shapes what
+counts as a vulnerability here.
+
+**In scope** — anything in `src/` that lets *ordinary* use go wrong: memory
+corruption, use-after-free, or a process crash reachable from normal API calls or
+from Lua code with no unusual privileges.
+
+**Not in scope:**
+
+- **Running untrusted Lua.** This library gives Lua scripts the full standard
+  library, including `os.execute`, `io.open` and `require`, plus LuaFileSystem. A Lua
+  script can therefore run commands and read and write files with the privileges of
+  your Node.js process. That is what embedding Lua means; it is not a defect in this
+  package. Do not feed it code you would not run yourself.
+- **Misusing the low-level stack API.** This is a thin wrapper over the Lua C API and
+  does not shield you from every misuse of it. Some operations on values of an
+  unexpected type raise an *unprotected* Lua error, which aborts the process rather
+  than throwing. `SetField` and `GetField` guard against this; other methods do not.
+  A crash reached that way is documented behaviour, not a vulnerability.
+- **Findings in `vendor/`.** Lua 5.1.5 and LuaFileSystem are vendored verbatim and are
+  not patched here. Report those upstream. If something in them is genuinely
+  exploitable through this package's API, do report it here as well.
