GitHub Actions pull_request workflow checkout fetch-depth 0 untrusted code secrets Git history security documentation

💡 Result:

In GitHub Actions, using fetch-depth: 0 alongside untrusted code, particularly within privileged workflow triggers, introduces significant security risks. Security Implications of fetch-depth: 0 Setting fetch-depth: 0 instructs actions/checkout to clone the entire commit history, branches, and tags of a repository [1][2]. This creates two primary risks: - Data Exposure: It may expose sensitive information—such as credentials, API keys, or proprietary data—that were removed from the repository in past commits but remain in the Git history [3]. - Increased Exfiltration Surface: If an attacker gains control of a runner (e.g., via a "pwn request" vulnerability), the full history provides a much larger volume of data they can exfiltrate [3]. Privileged Workflows and Untrusted Code Workflows using pull_request_target, workflow_run, issue_comment, or workflow_call run in a privileged context with access to repository secrets and write permissions [4][5]. - The "Pwn Request" Risk: Historically, attackers could open a pull request from a fork, trigger a pull_request_target workflow, and use actions/checkout to pull and execute the malicious code from that fork using the base repository's secrets [6][7]. - New Protections: As of June 2026, actions/checkout includes built-in protections that block the checkout of untrusted fork code when running under pull_request_target or workflow_run [6][7]. If your workflow requires this, you must explicitly set allow-unsafe-pr-checkout: true [1][7]. This flag should only be used after a thorough security review and confirmation that no untrusted code is executed [8][7]. Best Practices - Prefer pull_request for untrusted code: Use the standard pull_request trigger for builds and tests, as it operates in an unprivileged environment with read-only tokens and no access to secrets [9][6][4]. - Use workflow_run for privilege separation: If you must perform a privileged action (like commenting on a PR or deploying) based on the result of an untrusted build, use a two-step process [10][11]. Run the untrusted code in a pull_request workflow, output the results as an artifact, and then trigger a separate, privileged workflow_run to process that artifact [10][12]. - Minimize fetch-depth: Use fetch-depth: 1 by default [3]. Only use fetch-depth: 0 if the workflow strictly requires full history (e.g., for git describe or complex versioning) [13]. If you only need tags, use fetch-tags: true instead of cloning the entire history [13]. - Audit Workflows: Periodically scan for fetch-depth: 0 and the use of allow-unsafe-pr-checkout to ensure they are still necessary and correctly implemented [4][3].

Separate the full-history Gitleaks scan from PR-controlled execution.
Because this pull_request job executes PR-controlled installation and hooks after checking out fetch-depth: 0, historical Git objects, including removed secrets, are available to PR code; isolate Gitleaks, verify its archive, pin actions to commit SHAs, and add dependency-review and weekly OpenSSF Scorecard workflows.

Verify the Gitleaks archive before installation: the curl | tar pipeline installs an unverified release artifact, so a compromised release can execute in the CI job; download and verify the release checksum before sudo install.
