PAT Scopes are now Supported by all Azure DevOps REST APIs

Security Considerations For Your 2022 CI/CD Services Can Find Their Peace In Azure DevOps

The Azure DevOps team recently implemented a change to connect all of their REST APIs with a specific personal access token ( PAT ) scopes as part of their efforts to improve security. Before this change, some of these APIs were not tied to a PAT scopes, which could potentially lead to customers using full-scoped PATs to access them. Full-scoped PATs grant access to all the permissions of the corresponding user and could be misused by malicious actors to access sensitive information such as source code or production infrastructure. By associating these APIs with a PAT scope, the Azure DevOps team is reducing the risks associated with a compromised PAT credential.

If you are using a full-scoped personal access token (PAT) to authenticate to an Azure DevOps REST API, you should consider switching to a PAT with a more specific scope to limit access. The specific scopes accepted by each API are listed in the “Security” section of the API’s documentation. By using a PAT with the appropriate scope, you can avoid granting unnecessary access.

Additionally, these improvements should allow more customers to prevent the creation of full-scoped personal access tokens (PATs) by enabling the corresponding control plane policy.
