Opengrep — security.gha.run-shell-injection-inputs (WARNING)

A composite-action / reusable-workflow / workflow_dispatch inputs.* value is interpolated directly into this run/script block. Inputs are supplied by the caller, who may pass attacker-controlled data into them — e.g. a caller invoking this with version: ${{ github.event.pull_request.head.ref }} (a fork branch name). Because the input value is substituted before the shell runs, the callee cannot trust it. Defensive fix: copy the input into a step-level env: entry (e.g. VERSION: ${{ inputs.version }}) and reference the quoted environment variable in the script instead (echo "$VERSION"). This is advisory (WARNING): not every input carries untrusted data, but routing inputs through env: makes the component safe regardless of how callers use it. If an input appears only as a condition selecting between hard-coded string literals (e.g. ${{ inputs.flag && 'a' || 'b' }}), the emitted value is constant and that specific use is not exploitable — but hoist the condition into bash (set a boolean env: var and branch with if) so the run line carries no ${{ }} and the safety stays local and stable. Directly-untrusted github.* contexts are covered separately by security.gha.run-shell-injection.
