# zizmor runs static analysis over every workflow under .github/workflows
|
|
# looking for the well-known classes of GitHub Actions footguns: template
|
|
# injection from untrusted input, dangerous triggers like
|
|
# `pull_request_target`, unpinned `uses:` refs, excessive token scopes,
|
|
# secret exfil via job outputs, and a long tail of others.
|
|
#
|
|
# Findings at `low` confidence and above fail the job, so this acts as a
|
|
# blocking PR check. To deliberately allow a finding, suppress it in
|
|
# `.github/zizmor.yml` with a justification — never silently ignore.
