+# Security policy
+
+## Reporting a vulnerability
+
+Please report security problems privately through GitHub:
+**[Report a vulnerability](https://github.com/storytold/wordcraft/security/advisories/new)**
+(Security tab › Advisories › Report a vulnerability).
+
+Don't open a public issue or pull request for a vulnerability until a fix is released.
+
+Useful to include:
+- the WordCraft version or commit, and the platform (macOS, Windows, Linux, BSD, web);
+- what an attacker can do, and what they need (a crafted document, MCP or control-channel access, a local account…);
+- steps or a sample file that reproduce it.
+
+We'll acknowledge the report, keep you updated while we work on a fix, and credit you in the advisory unless you'd rather not be named.
+
+## Supported versions
+
+Fixes go into `main` and ship in the next release. Older releases don't get backported fixes.
+
+## Scope
+
+In scope: anything that lets a document, file, command, MCP or control-channel request, or network response read or write files it shouldn't, run code, leak data, or crash WordCraft and lose the user's work.
+
+Crashes from hostile input count, because WordCraft treats every panic as a bug (see [Never crash](AGENTS.md)).
