From ee53fbe1172e98ae13a99951074f125a57914cf8 Mon Sep 17 00:00:00 2001 From: vivekchand Date: Wed, 9 Sep 2026 16:38:22 +0000 Subject: [PATCH] Harden CI: pin sync-github-about's actions and drop the job credential sync-github-about.yml landed on main today (#5762) with `actions/checkout@v4` and `actions/setup-python@v5`. Both are floating tags, and they were the only two unpinned `uses:` references left in the repository -- the other 65 checkout and 52 setup-python references are already pinned to a commit SHA. A tag is mutable: whoever owns the action's repository can repoint it at new code, which then runs inside our job. Pinned to the same SHAs every other workflow here already uses, so nothing new is introduced and the version comment stays readable. The checkout also now sets `persist-credentials: false`. This job never pushes with the job credential -- it reads the tree and writes the About blurb through the API with REPO_ADMIN_TOKEN -- so leaving GITHUB_TOKEN in .git/config handed it to every later step for no reason. 60 of the repo's 67 checkouts already set this; the ones that do not are the workflows that genuinely push with the job credential, which this is not. No behaviour change: same actions, same steps, same trigger. No-PRD: CI-only change, .github/ is exempt per scripts/check_product_record.py.
