CVE-2020-12690

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.

CVE-2020-12689

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.

CVE-2019-19687

OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false. Users with a role on a project are able to view any other users' credentials, which could (for example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope set to false are affected. (There will be a slight performance impact for the list credentials API once this issue is fixed.)

5.3 CVSS
CVE-2018-20170

OpenStack Keystone through 14.0.1 has a user enumeration vulnerability because invalid usernames have much faster responses than valid ones for a POST /v3/auth/tokens request. NOTE: the vendor's position is that this is a hardening opportunity, and not necessarily an issue that should have an OpenStack Security Advisory

5.3 CVSS
CVE-2018-14432

In the Federation component of OpenStack Keystone before 11.0.4, 12.0.0, and 13.0.0, an authenticated "GET /v3/OS-FEDERATION/projects" request may bypass intended access restrictions on listing projects. An authenticated user may discover projects they have no authority to access, leaking all projects in the deployment and their attributes. Only Keystone with the /v3/OS-FEDERATION endpoint enabled via policy.json is affected.

CVE-2015-9240

Due to a bug in the the default sign in functionality in the keystone node module before 0.3.16, incomplete email addresses could be matched. A correct password is still required to complete sign in.
