+# Security Policy
+
+## Scope
+
+This repository is a project template. It ships GitHub Actions workflows,
+dependency declarations and configuration that are copied into other people's
+projects, so a problem here propagates to everything generated from it.
+
+Reports about the template itself are in scope: a workflow that leaks
+credentials, an over-permissioned token, a dependency pinned to something
+malicious, or a generated default that is unsafe.
+
+## Supported versions
+
+The latest tag receives fixes. Older tags do not.
+
+## Reporting a vulnerability
+
+Please **do not** open a public issue.
+
+Report privately through
+[GitHub Security Advisories](https://github.com/leynier/python-template/security/advisories/new),
+or by email to <leynier41@gmail.com>.
+
+Please include:
+
+- What the problem is and what an attacker could do with it.
+- Which file or generated output is affected.
+- Steps to reproduce, ideally the `copier` answers that produce the bad output.
+
+You can expect an initial response within 7 days.
+
+## Security posture of this repository
+
+- GitHub Actions are pinned to release tags, and
+  [zizmor](https://github.com/zizmorcore/zizmor) audits every workflow on
+  change. The pinning policy is declared in `zizmor.yml`.
+- Workflows declare least-privilege `permissions:`.
+- Dependabot has a cooldown before adopting newly published releases.
+- CodeQL and OpenSSF Scorecard run against this repository.
+
+Generated projects get the same treatment, plus PyPI Trusted Publishing with
+Sigstore attestations instead of long-lived API tokens.
