Bumps [step-security/harden-runner](https://github.com/step-security/harden-runner) from 2.19.0 to 2.19.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/step-security/harden-runner/releases">step-security/harden-runner's releases</a>.</em></p> <blockquote> <h2>v2.19.1</h2> <h2>What's Changed</h2> <ul> <li>fix: detect ubuntu-slim runners early and bail out by <a href="https://github.com/devantler"><code>@devantler</code></a> in <a href="https://redirect.github.com/step-security/harden-runner/pull/657">step-security/harden-runner#657</a></li> </ul> <p>What the fix changes</p> <ul> <li>Harden-Runner will detect <code>ubuntu-slim</code> runners and exit cleanly with an informational log message, instead of post harden runner step failing on chown: invalid user: 'undefined'.</li> </ul> <p>What the fix does not do</p> <ul> <li>Jobs running on <code>ubuntu-slim</code> will not be monitored by Harden-Runner. The agent relies on kernel-level features (that require elevated capabilities).</li> <li>Per GitHub's docs on <a href="https://docs.github.com/en/actions/reference/runners/github-hosted-runners#single-cpu-runners">single-CPU runners</a>: "The container for ubuntu-slim runners runs in unprivileged mode. This means that some operations requiring elevated privileges such as mounting file systems, using Docker-in-Docker, or accessing low-level kernel features are not supported." Those low-level kernel features are what the agent needs, so monitoring inside the unprivileged container is not feasible today.</li> </ul> <p>For StepSecurity enterprise customers If your security posture requires that workflows are always monitored, you can block the use of <code>ubuntu-slim</code> via workflow run policies see the <a href="https://docs.stepsecurity.io/workflow-run-policies/policies#runner-label-policy">Runner Label Policy</a> docs. This lets you enforce that jobs only run on monitored runner types.</p> <h2>New Contributors</h2> <ul> <li><a href="https://github.com/devantler"><code>@devantler</code></a> made their first contribution in <a href="https://redirect.github.com/step-security/harden-runner/pull/657">step-security/harden-runner#657</a></li> </ul> <p><strong>Full Changelog</strong>: <a href="https://github.com/step-security/harden-runner/compare/v2.19.0...v2.19.1">https://github.com/step-security/harden-runner/compare/v2.19.0...v2.19.1</a></p> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/step-security/harden-runner/commit/a5ad31d6a139d249332a2605b85202e8c0b78450"><code>a5ad31d</code></a> Merge pull request <a href="https://redirect.github.com/step-security/harden-runner/issues/657">#657</a> from devantler/fix/ubuntu-slim-user-env</li> <li><a href="https://github.com/step-security/harden-runner/commit/6e928567d74554b8842dd434908da31c593ba85c"><code>6e92856</code></a> build dist and trim ubuntu-slim message</li> <li><a href="https://github.com/step-security/harden-runner/commit/4e0504ee086374bdec7064e5c26d48af41ba6209"><code>4e0504e</code></a> Merge branch 'main' into fix/ubuntu-slim-user-env</li> <li><a href="https://github.com/step-security/harden-runner/commit/376d25a97f3a1640ff8cbbddaa4af25948df2cf3"><code>376d25a</code></a> fix: detect ubuntu-slim runners early and bail out</li> <li>See full diff in <a href="https://github.com/step-security/harden-runner/compare/8d3c67de8e2fe68ef647c8db1e6a09f647780f40...a5ad31d6a139d249332a2605b85202e8c0b78450">compare view</a></li> </ul> </details> <br /> [](https://docs.github.com/en/github/managing-security-vulnerabilities/about-dependabot-security-updates#about-compatibility-scores) Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself.
