Change Summary:

• Update Docker Buildx action from commit 988b5a0 to c47758b, maintaining the same major version (v3)

Potential Vulnerability:

• File: .github/workflows/ci.yaml:39
• Code: uses: docker/setup-buildx-action@c47758b77c9736f4b2ef4073d4d51994fabfe349
• Explanation: Using commit hashes for GitHub Actions is generally secure, but upgrading action versions without thorough testing could introduce potential security risks. While pinning to a specific commit is a good security practice, changes between commits should be reviewed.

Code Smell:

• No code smells identified in this change.

Debug Log:

• No debug logs present in this change.

Unintended Consequences:

• File: .github/workflows/ci.yaml:39
• Code: uses: docker/setup-buildx-action@c47758b77c9736f4b2ef4073d4d51994fabfe349
• Explanation: Updating the buildx action version could potentially impact CI pipeline behavior if there are breaking changes or new dependencies between the commits. While both commits are tagged as v3, internal implementation changes might affect build outcomes.

Risk Score: 3

• The risk is relatively low as this is a version update within the same major version of a well-maintained GitHub Action
• The use of commit hashes provides good security control
• The docker/setup-buildx-action is a widely used and trusted action
• The change is isolated to the CI pipeline and doesn't affect production code directly
