A user who can run a workflow could use the job's token with `GET /api/v1/user/repos` to list every repository on the instance, including private repositories of other users and organizations, with their metadata. Repository contents remained protected by per-repository permission checks. System users now own nothing, and `/api/v1/user` routes other than `GET /api/v1/user` accept only individual and bot accounts."}], "lastModified": "2026-11-01T10:18:34.510", "sourceIdentifier": "88ee5874-cf24-4952-aea0-31affedb7ff2"}
