Summary
Supply chain attacks are lately one of the most practical ways to compromise CI: an action can be pinned, but the binary it downloads at runtime can still change upstream. Adding a checksum input lets users pin both the action code and the downloaded release asset, so workflows fail closed if that binary is replaced, corrupted, or unexpectedly modified.
checksuminputWhy
This action downloads a release archive during CI. Pinning the action SHA fixes the action code, but it does not pin the release asset that gets fetched later. A checksum input gives security-sensitive workflows a simple way to make that binary download fail closed if the asset changes unexpectedly.
