Replace references to endpoints listed as deprecated by it’s replacement. See Details section. The updated APIs can be found in https://www.elastic.co/docs/api/doc/kibana/group/endpoint-alerting. ::::

:::{dropdown} Removed legacy cases endpoints

• GET /api/cases/status has been deprecated with no replacement. Deleted in v9.0.0
• GET /api/cases/{{case_id}}/comments has been replaced by GET /api/cases/{{case_id}}/comments/_find released in v7.13
• GET /api/cases/<case_id>/user_actions has been replaced by GET /api/cases/<case_id>/user_actions/_find released in v8.7
• includeComments parameter in GET /api/cases/{{case_id}} has been deprecated. Use GET /api/cases/{{case_id}}/comments/_find instead, released in v7.13

Impact
Deprecated endpoints will fail with a 404 status code starting from version 9.0.0.

Action
Remove references to GET /api/cases/status endpoint. Replace references to deprecated endpoints with the replacements listed in the breaking change details. ::::

:::{dropdown} Removed all security v1 endpoints All v1 Kibana security HTTP endpoints have been removed.

GET /api/security/v1/logout has been replaced by GET /api/security/logout GET /api/security/v1/oidc/implicit has been replaced by GET /api/security/oidc/implicit GET /api/security/v1/oidc has been replaced by GET /api/security/oidc/callback POST /api/security/v1/oidc has been replaced by POST /api/security/oidc/initiate_login POST /api/security/v1/saml has been replaced by POST /api/security/saml/callback GET /api/security/v1/me has been removed with no replacement.

For more information, check #199656.

Impact
Any HTTP API calls to the v1 Kibana security endpoints will fail with a 404 status code starting from version 9.0.0. Third party OIDC and SAML identity providers configured with v1 endpoints will no longer work.

Action
Update any OIDC and SAML identity providers to reference the corresponding replacement endpoint listed above. Remove references to the /api/security/v1/me endpoint from any automations, applications, tooling, and scripts. ::::

:::{dropdown} Access to all internal APIs is blocked Access to internal Kibana HTTP APIs is restricted from version 9.0.0. This is to ensure that HTTP API integrations with Kibana avoid unexpected breaking changes. Refer to #193792.

Impact
Any HTTP API calls to internal Kibana endpoints will fail with a 400 status code starting from version 9.0.0.

Action
Do not integrate with internal HTTP APIs. They may change or be removed without notice, and lead to unexpected behaviors. If you would like some capability to be exposed over an HTTP API, create an issue. We would love to discuss your use case. ::::

:::{dropdown} Remove original user and host risk scoring and all associated UIs The original host and risk score modules have been superseded since v8.10.0 by the Risk Engine.

In 9.0.0 these modules are no longer supported, the scores no longer display in the UI and all UI controls associated with managing or upgrading the legacy modules have been removed.

Impact
As well as the legacy risk scores not being shown in the UI, alerts no longer have the legacy risk score added to them in the <host|user>.risk.calculated_level and <host|user>.risk.calculated_score_norm fields.

The legacy risk scores are stored in the ml_host_risk_score_<space_id> and ml_user_risk_score_<space_id> indices, these indices will not be deleted if the user chooses not to upgrade.

Legacy risk scores are generated by the following transforms:

• ml_hostriskscore_pivot_transform_<space_id>
• ml_hostriskscore_latest_transform_<space_id>
• ml_userriskscore_pivot_transform_<space_id>
• ml_userriskscore_latest_transform_<space_id>

If a user does not upgrade to use the Risk Engine, these transforms will continue to run in 9.0.0, but it will be up to the user to manage them.

Action
Upgrade to use the Risk Engine in all spaces which use the legacy risk scoring modules:

• In the main menu, go to Security > Manage > Entity Risk Score.
• If the original user and host risk score modules are enabled, you’ll see a button to "Start update". Click the button, and follow the instructions. ::::

:::{dropdown} Reporting uses Kibana feature privileges only to control access to reporting features In 8.x, the default access control model was based on a built-in role called reporting_user, which granted access to reporting features. Since 7.13, the preferred model for controlling access to reporting features has been Kibana feature privileges, enabled by setting xpack.reporting.roles.enabled: false in kibana.yml.

In 9.0.0, the xpack.reporting.roles.* settings will be ignored.

Impact
The built-in reporting_user role is no longer deprecated and provides access to reporting features using Kibana feature privileges. This means that users that do not have privileges to use reporting will not see reporting features in the Kibana UI.

Action
Use Kibana feature privileges to control access to reporting features. For more information, see #200834.

• The reporting_user role is still supported, but gives full access to all reporting features. We recommend creating custom roles with minimal privileges in Stack Management > Roles.
• The xpack.reporting.roles.allow setting is no longer supported. If you have a xpack.reporting.roles.allow value in your kibana.yml, you should remove this setting and assign privileges to reporting features using Kibana feature privileges. ::::

:::{dropdown} Saved query privileges have been reworked Saved query privileges have been reworked to rely solely on a single global savedQueryManagement privilege, and eliminate app-specific overrides (e.g. implicit access with all privilege for Discover, Dashboard, Maps, and Visualize apps). This change simplifies the security model and ensures consistency in the saved query management UI across Kibana, but results in different handling of saved query privileges for new user roles, and minor breaking changes to the existing management UX. For more information, check #202863.

Impact
The savedQueryManagement feature privilege now globally controls access to saved query management for all new user roles. Regardless of privileges for Discover, Dashboard, Maps, or Visualize, new user roles follow this behaviour: . If savedQueryManagement is none, the user cannot see or access the saved query management UI or APIs. . If savedQueryManagement is read, the user can load queries from the UI and access read APIs, but cannot save queries from the UI or make changes to queries through APIs. . If savedQueryManagement is all, the user can both load and save queries from the UI and through APIs.

Action
Existing user roles that were previously implicitly granted access to saved queries through the dashboard, discover, visualize, or maps feature privileges will retain that access to prevent breaking changes. While no action is required for existing roles, it’s still advisable to audit relevant roles and re-save them to migrate to the latest privileges model. For new roles, ensure that the savedQueryManagement privilege is set as needed. ::::
