CWE-863Incorrect Authorization

Description

An issue was discovered in OpenStack Keystone before 29.0.3. Tokens obtained via delegated authentication methods (EC2 credentials, application credentials, OAuth1 access tokens, and trusts) are not blocked from creating, modifying, or deleting credentials via the /v3/credentials API. EC2-derived tokens can additionally read credential blobs, exposing TOTP MFA seeds and other secrets. Also, PATCH /v3/credentials does not validate the requested post-update project_id, allowing any delegated token to move a credential to an unauthorized project. All Keystone deployments using delegated authentication are affected.
