Fix cross-target toolchain setup - #26
Conversation
WalkthroughThe action now uses the selected host Rust toolchain for the requested target. It adds the target with Merge Risk: 🟡 Moderate · up to The matrix builds an external repository while checkout credentials remain persisted, creating a material risk that build code could use the token for Git operations. This should be fixed before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

official actions/checkout persist-credentials default README
💡 Result:
The persist-credentials input for the official actions/checkout GitHub Action has a default value of true [1][2]. 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][3][2]. This allows subsequent steps in your workflow to execute authenticated git commands (such as git fetch or git push) automatically [1][3]. The credentials are removed during the post-job cleanup [1][3]. In recent versions of actions/checkout, the implementation of this persistence has been improved for security; credentials are now stored in a separate file within $RUNNER_TEMP rather than directly in .git/config [1][4]. If you wish to prevent the action from persisting these credentials, you can explicitly set persist-credentials to false in your workflow configuration [1][3].

Sensitive Data Exposure
CWE: CWE-522 — Insufficiently Protected Credentials
Do not retain checkout credentials during the build.
The local action runs cargo in the checked-out external project. If its build scripts or dependencies run Git commands, persisted checkout credentials can authenticate those commands. Set persist-credentials: false on both checkout steps.
