ci(content): scope the org-admin PAT to a main-only environment - #2734
Merged
Conversation
CONTENT_BOT_TOKEN is an org admin — it has to be, because merging a content publish relies on the ruleset bypass. As a plain repo secret it was readable by anyone with write access to this repo: twelve workflows here carry `workflow_dispatch`, and a dispatch runs the workflow FROM THE DISPATCHED REF. Push a branch whose workflow echoes the secret, dispatch that branch, and the token is yours. Removing `workflow_dispatch` from one file fixes nothing, since the attacker supplies their own workflow. Move it behind the `content-publish` environment instead, whose deployment branch policy allows `main` only. Every job that legitimately needs it already runs from main — `repository_dispatch`, `pull_request_target` and `workflow_run` all resolve `github.ref` to the default branch — so the three jobs keep working while any other ref is refused the secret outright. This lands the `environment:` keys only. The repo-level copies still exist and still win, so nothing changes yet; the token has to be re-added as an environment secret by hand (secrets are write-only, it cannot be copied) and the repo-level ones deleted before this takes effect.

by update-content.yml to include CONTENT_BOT_SIGNING_KEY before removing the
repository-level secret, preserving the workflow’s existing behavior when the
key is unavailable. Remove repository-level CONTENT_BOT_SIGNING_KEY and

Migrate CONTENT_BOT_SIGNING_KEY before deleting the repository secret.
update-content.yml exits when this key is unavailable, so content publishing will stop if the repository-level secret is removed before the key is confirmed on the content-publish environment. Add or verify the environment secret, then complete one real publish before deleting the repository-level copy.

Summary
CONTENT_BOT_TOKENis an org-admin PAT and has to be — merging a content publish depends on the ruleset bypass. As a plain repo secret, anyone with write access to peanut-ui can read it: 12 workflows here carryworkflow_dispatch, and a dispatch runs the workflow from the dispatched ref. Push a branch whose workflow echoes the secret, dispatch that branch, done. Droppingworkflow_dispatchfrom one file fixes nothing — the attacker brings their own workflow.This moves it behind the
content-publishenvironment, whose deployment branch policy allowsmainonly. All three jobs that legitimately need it already run from main (repository_dispatch,pull_request_targetandworkflow_runall resolvegithub.refto the default branch), so they keep working while any other ref is refused the secret.Found while auditing unverified commits across the org (TASK-21002); unrelated to signing, and pre-existing.
This PR alone changes nothing
It lands the
environment:keys. Repo-level secrets remain and still take precedence, so the pipeline behaves exactly as today. Two manual steps finish it:CONTENT_BOT_TOKENas a secret on thecontent-publishenvironment (by hand — secrets are write-only, so it cannot be copied programmatically).CONTENT_BOT_TOKENandCONTENT_BOT_SIGNING_KEY.CONTENT_BOT_SIGNING_KEYis already in the environment.Risk
Low while unmerged-and-unfinished; the real risk is step 2. If the environment lacks the token when the repo-level copy is deleted, content publishing stops — loudly, and the manual
publish-to-prod.shpath still works. Verify with one real publish before deleting.Screenshots: N/A (CI only).
