Summary
This PR fixes a script injection vulnerability in the get-compose-action by using an environment variable to pass
inputs.versioninstead of direct interpolation in the run script.Changes
env:block to storeinputs.versioninCOMPOSE_VERSIONenvironment variable"$COMPOSE_VERSION"instead of${{ inputs.version }}Security Impact
The original code used direct variable interpolation which could potentially allow an attacker to inject malicious code. By using an intermediate environment variable with proper quoting, the value is treated as data and cannot be executed as code.
