CVE-2026-80182

Quick assessment

Affected
OpenStack Keystone
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 OpenStack Keystone 版本低于 29.0.3 中，通过 OAuth1 访问令牌、应用凭据或信任范围（trust-scoped）认证获取的令牌，能够创建新的长期有效凭据或授权新的委派，而这些新创建的凭据或委派可以独立于获取它们的原始凭据存在，并且其生命周期可以超过原始凭据。 用于阻止此类操作的委派限制并未一致地适用于所有类型的委派令牌。例如，OAuth1 作用域的令牌（OAuth1-scoped token）可以创建应用凭据或授权 OAuth1 请求令牌，尽管对于其他类型的委派令牌，这些操作是受限

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
In OpenStack Keystone before 29.0.3, tokens obtained via OAuth1 access token, application credential, or trust-scoped authentication could create new long-lived credentials or authorize new delegations that persist independently of, and outlive, the credential used to obtain them. The delegation restrictions that block these operations did not consistently apply to all delegated token types, allowing an OAuth1-scoped token, for example, to create application credentials or authorize OAuth1 request tokens despite those operations being restricted for other delegated token types. All Keystone deployments that permit delegated authentication through OAuth1 access tokens, application credentials, or trusts are affected.
