Preliminary research
Sub:jugation — Hijacking Cloud Identities by Recycling Namespaces in Global OIDC Issuers
AI-collected research leads through 6 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
CI/CD platforms mint OIDC tokens from a single global issuer, and the sub claim is built entirely from a repository namespace that GitHub, GitLab and Terraform allow anyone to re-register once deleted. Recreating the path yields a token with an identical sub, so any cloud IAM role still trusting it can be assumed. Scanning showed 14% of AWS and 24% of Azure trusted namespaces unclaimed, and GitHub Code Search finds workflows with cleartext role ARNs to target.
