| CVE-2020-12691 | Hig | 0.51 | 8.8 | 0.05 | May 7, 2020 | An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to… | ||
| CVE-2020-12690 | Hig | 0.50 | 8.8 | 0.02 | May 7, 2020 | 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… | ||

The highest threat from this vulnerability is to data confidentiality and… | ||
| CVE-2026-43001 | Hig | 0.44 | 7.9 | 0.00 | May 1, 2026 | An issue was discovered in OpenStack Keystone before 29.0.2. POST /v3/credentials did not validate that the caller-supplied project_id for an EC2-type credential matched the project of the authenticating application credential. This allowed an attacker holding an unrestricted… | ||
| CVE-2026-40683 | Hig | 0.43 | 7.7 | 0.00 | Apr 14, 2026 | In OpenStack Keystone before 28.0.1, the LDAP identity backend does not convert the user enabled attribute to a boolean when the user_enabled_invert configuration option is False (the default). The _ldap_res_to_model method in the UserApi class only performed string-to-boolean… | ||
| CVE-2022-2447 | Med | 0.43 | 6.6 | 0.01 | Sep 1, 2022 | A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than… | ||
| CVE-2021-38155 | Hig | 0.42 | 7.5 | 0.02 | Aug 6, 2021 | OpenStack Keystone 10.x through 16.x before 16.0.2, 17.x before 17.0.1, 18.x before 18.0.1, and 19.x before 19.0.1 allows information disclosure during account locking (related to PCI DSS features).

The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times. | ||
| CVE-2018-20170 | Med | 0.35 | 5.3 | 0.01 | Dec 17, 2018 | 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… | ||
| CVE-2026-44394 | Med | 0.32 | 6.0 | 0.00 | May 28, 2026 | An issue was discovered in OpenStack Keystone before 29.0.2.

The… | ||
| CVE-2026-42999 | Med | 0.32 | 6.0 | 0.00 | May 28, 2026 | An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone RBAC policy enforcer in enforce_call unconditionally merges the raw JSON request body into the policy enforcement dictionary via policy_dict.update(json_input.copy()), overwriting trusted target data that… | ||
| CVE-2026-42998 | Med | 0.32 | 6.0 | 0.00 | May 28, 2026 | An issue was discovered in OpenStack Keystone before 29.0.2.
