| GitHub workflows can be triggered through various repository events, including incoming pull requests (PRs) or comments on Issues/PRs. A potentially dangerous misuse of the triggers such as `pull_request_target` or `issue_comment` followed by an explicit checkout of untrusted code (Pull Request HEAD) may lead to repository compromise if untrusted code gets executed (e.g., due to a modified build script) in a privileged job. | ||||||

| * Fixed help file descriptions for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`, `actions/untrusted-checkout/medium`. Previously the messages were unclear as to why and how the vulnerabilities could occur. Additionally alter 2 patterns in the detection such that now extra sinks are detected in the following cases: scripts executed via python modules and `go run` in directories are detected as potential mechanisms of injection. This may lead to more results being detected by all 3 queries. | ||||||

| * Fixed the help file descriptions for `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`, and `actions/untrusted-checkout/medium`. Previously, the messages did not clearly explain why and how the vulnerabilities could occur. Also updated two detection patterns so that additional sinks are detected. In particular, scripts executed via Python modules and `go run` in directories are now detected as potential injection mechanisms. This may lead to more results from all three queries. |

The Overview text says "least privileges" but the standard phrasing is "least privilege" (singular). Consider also changing "whether least privileges is used" to something grammatically correct like "whether the principle of least privilege is followed".
