Upgrade actions/checkout v3->v7 and actions/setup-python v4->v7 to resolve Node 20 deprecation and enable built-in pwn request protection. Move attacker-controllable inputs from direct shell interpolation to env variables to prevent script injection. Add persist-credentials: false to prevent token leakage via .git/config. Files changed: - commit_to_pullrequest/action.yml - ansible_validate_changelog/action.yml - workflows/changelog.yml Assisted-by: Claude Opus 4.6
Pin actions/checkout and actions/setup-python to their v7.0.0 commit SHAs to prevent supply-chain attacks via tag mutation. Assisted-by: Claude Opus 4.6

Address PR review: pass inputs.token to checkout for private fork access, and authenticate via gh CLI before push since persist-credentials: false removes stored git credentials. Assisted-by: Claude Opus 4.6
