  "summary": "CVE-2026-44394 is fixed in 3 products on 1 platform, first by keystone 2:29.0.0-0ubuntu1.2, released May 28, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "keystone: An issue was discovered in OpenStack Keystone before 29.0.2",
  "description": "An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone federated token rescoping mechanism does not propagate the original token\u0027s expiry to the newly issued token. When a federated user rescopes a token via POST /v3/auth/tokens, the handle_scoped_token() function in the mapped authentication plugin returns response data without an expires_at value. The token provider falls back to issuing a token with a fresh default TTL. By rescoping repeatedly before each token expires, a user can maintain access indefinitely, bypassing operator-configured token lifetime policies. This is a variant of CVE-2012-3426. Only deployments using federated identity (SAML2, OpenID Connect) are affected.",
