Fix command injection in release workflow (CVE)#677
Merged
Conversation
Move github.event.inputs.tag from direct shell interpolation to env
variables in all jobs (linux, musllinux, windows, macos, sdist,
github-release). Direct ${{ }} interpolation in run: blocks allows
arbitrary command execution via crafted tag inputs.
