upbound/platform-ref-aws #211

Change Summary:

• Ubuntu runner version update from 22.04 to 24.04 across multiple GitHub Actions workflows (ci.yaml and tag.yml)

Potential Vulnerability:

• File: .github/workflows/ci.yaml:17
• Code: runs-on: ubuntu-24.04
• Explanation: Ubuntu 24.04 is not yet officially released (as of early 2024) and using a non-existent or pre-release version in GitHub Actions could lead to workflow failures or unpredictable behavior. This could potentially impact the security and stability of the CI/CD pipeline.

Code Smell:
None identified in the current changes.

Debug Log:
None identified in the current changes.

Unintended Consequences:

• File: .github/workflows/ci.yaml:17,28
• Code:

runs-on: ubuntu-24.04

• Explanation: Changing the Ubuntu version across CI workflows could lead to:

  1. Immediate pipeline failures due to non-existent runner version
  2. Different package versions or dependencies compared to ubuntu-22.04
  3. Potential incompatibilities with existing build scripts or dependencies
  4. Inconsistency with development environments if they're still on 22.04

• File: .github/workflows/tag.yml:15

• Code: runs-on: ubuntu-24.04

• Explanation: The tagging workflow is critical for release management. Using an unreleased Ubuntu version could impact the reliability of the release process and potentially affect production deployments.

Risk Score: 8
The high risk score is warranted because:

1. The change affects critical CI/CD infrastructure
2. It modifies both build and release workflows
3. It references a non-existent Ubuntu version
4. The changes could immediately break the entire CI/CD pipeline
