Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to This PR pins workflow actions to immutable commits and moves affected jobs to GitHub-hosted runners. The pinning improves supply-chain integrity, while the runner change alters where privileged automation executes without established equivalent isolation controls; the PR is mergeable with explicit owner awareness of this bounded security risk.

Rust toolchain SHA pin is unsafe
Medium Severity
Pinning dtolnay/rust-toolchain to a stable ref SHA without a toolchain input is unsafe. That action force-pushes stable, so GitHub eventually garbage-collects the commit and the action cannot be resolved. The rust CI job, macOS preview, and release builds then fail, and there is no rust-toolchain.toml to fall back on.

Rust pin drops toolchain channel
High Severity
Pinning dtolnay/rust-toolchain to a commit SHA removes the @stable ref that action uses to choose a Rust version, and these steps still omit the toolchain input. The action then fails because toolchain is required when the ref is not a channel name, which breaks the rust job and resource-monitor builds on a cache miss.

actions/checkout persist-credentials default true README
💡 Result:
In the GitHub actions/checkout action, the persist-credentials input defaults to true [1][2][3]. When set to true (the default), the action configures the authentication token or SSH key used to fetch the repository into the local Git configuration [1][2][3]. This allows subsequent steps in your workflow to execute authenticated Git commands (such as pushing changes) without needing to manually re-authenticate [1][2]. The action automatically removes these credentials during the post-job cleanup phase [1][2]. If you wish to prevent the action from persisting these credentials in the local Git configuration, you can explicitly set this input to false in your workflow file [1][2][3]: - uses: actions/checkout@v4 with: persist-credentials: false While the default behavior has been a subject of security discussions within the community regarding credential exposure, recent versions of the action have improved security by adjusting where and how these credentials are stored [4]. Users requiring a strictly least-privilege approach or those concerned about credential exposure in complex environments often choose to set this to false and manage authentication manually if needed [1][2].

Sensitive Data Exposure (CWE-522): Insufficiently Protected Credentials

Disable checkout credential persistence before running pull-request code.
Set persist-credentials: false on actions/checkout. The subsequent local git checkout uses the fetched history and does not need persisted credentials.

actions/create-github-app-token v2.2.2 README owner repositories permission-contents default permissions
💡 Result:
In the actions/create-github-app-token action, version 2.2.2, the following details apply regarding owner, repositories, and permission inputs: Owner and Repositories The owner input specifies the owner of the GitHub App installation and defaults to the current repository owner [1]. The repositories input accepts a comma or newline-separated list of repositories to which the token should be granted access; if left unset, it defaults to the current repository [1]. Permissions and Defaults By default, the generated access token inherits all of the permissions configured for the app installation [2][3][4]. Regarding the permission-contents input (and all other permission- prefixed inputs), it allows you to explicitly define the access level granted to the token for that specific scope (e.g., repository contents, commits, branches, releases) [1][5]. These inputs can be set to 'read' or 'write' [1][5]. While the action defaults to inheriting the installation's full permissions, it is explicitly recommended to list only the permissions required for your specific use case to follow the principle of least privilege [2][3][6]. Note that if you attempt to set a permission that the app installation does not possess, the action will result in an error [2][3][6]. Installation permissions themselves are defined when the app is installed on an account; any subsequent additions to an app's permissions require approval from an account administrator before they take effect on the installation [2][3][4].

When owner is set without repositories, the action grants the token access to all repositories in that owner’s installation. Unspecified permission inputs also inherit the installation permissions.
