Pins the default GITHUB_TOKEN to contents: read on the workflows in .github/workflows/ that don't call a GitHub API beyond the initial checkout. The other workflows in this directory are left implicit because they need write scopes that a maintainer is better placed to declare. Motivation: CVE-2025-30066 (March 2025 tj-actions/changed-files compromise) exfiltrated GITHUB_TOKEN from workflow logs. Per-workflow caps bound runtime authority irrespective of repo or org default, give drift protection if the default ever widens, and are credited per-file by the OpenSSF Scorecard Token-Permissions check. YAML validated locally with yaml.safe_load. Signed-off-by: Arpit Jain <arpitjain099@gmail.com>

CVE-2025-30066 (March 2025
tj-actions/changed-filessupply-chain compromise) exfiltratedGITHUB_TOKENfrom workflow logs. Pinning per workflow caps runtime authority irrespective of the repo or org default, gives drift protection if the default ever widens, and is credited per-file by the OpenSSF ScorecardToken-Permissionscheck.YAML validated locally with
yaml.safe_loadon each touched file.Note
Low Risk
Low risk CI-only change that reduces
GITHUB_TOKENprivileges; should only affect workflows that needed broader permissions (not expected here).Overview
Adds workflow-level
permissions: contents: readto six GitHub Actions workflows (ci.yml,code-style.yml,dockers.yml,asan.yml,tsan.yml,ubsan.yml) to explicitly scope the defaultGITHUB_TOKENto read-only repository contents.Reviewed by Cursor Bugbot for commit 26d28ac.
