8.7.1edit

Known issuesedit

  • After upgrading Elastic prebuilt rules, some rules are erroneously duplicated as custom rules. To remove them, go to the Rules page (Manage → Rules), click the Custom rules filter next to the search bar, then select and delete the duplicate rules.
  • Index aliases and some data streams are not properly retrieved by the Elastic Security default data view.
  • The Add exceptions flyout loads indefinitely and an out of memory error displays when a rule has a large number of unmapped fields in multiple indices. To avoid this issue, use the exception APIs to manage exceptions.

  • If you modify an exception item using the update exception item API and only specify its item_id, the exception item is erroneously duplicated. To avoid this issue, you can either:

    If you’ve already encountered this issue and want to find erroneously duplicated exceptions, use the queries provided below.

    • Query for finding exception documents that were duplicated from only specifying the item_id:

      // Retrieve exception documents grouped by `item_id`.
// Each bucket contains all duplicates of that document.
GET .kibana*/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "match": {
            "type": "exception-list"
          }
        }
      ]
    }
  },
  "aggs": {
    "item_id_duplicates": {
      "terms": {
        "field": "exception-list.item_id",
        "min_doc_count": 2
      },
      "aggs": {
        "ids": {
          "top_hits": {
            "size": 100, // Increase this if you may have more duplicates.
            "_source": false
          }
        }
      }
    }
  },
  "size": 0
}

    • Query for finding exception documents that were duplicated and have lost their item_id because their id was used to update them:

      // Each item returned lost its `item_id`, which is expected to be present and unique.
GET .kibana*/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "term": {
            "exception-list.list_type": "item"
          }
        }
      ],
      "must_not": [
        {
          "exists": {
            "field": "exception-list.item_id"
          }
        }
      ]
    }
  }
}

Enhancementsedit

There are no user-facing changes in 8.7.1.

Bug fixesedit

  • Fixes a bug that caused the Elastic Agent upgrade from 8.6.2 to 8.7.0 to fail for Elastic Agents running the Osquery Manager integration (#2448).

    To prevent upgrade issues while upgrading Elastic Agent from 8.6.2 or 8.7.0, delete the Osquery Manager integration from your Elastic Agents before upgrading them, then re-add it after upgrading.

    If you already upgraded your Elastic Agents and they’re stuck in the Updating state, you’ll need to upgrade them using the API instead of Fleet. First, remove the Osquery integration from the Elastic Agents, then use the Agent upgrade API to start the upgrade. After the upgrade completes, add the Osquery Manager integration to the Elastic Agents again.

  • Fixes a UI bug that affected the rule details page when rules had long queries (#153338).
  • Fixes exception operator logic for mapping field conflicts (#155071).
  • Fixes a bug that stopped Elastic Defend from working when malware protection was enabled on Linux hosts.

  • Fixes a bug that prevented policy artifacts from being properly updated after being added to the .fleet-artifacts index (#154810).

    If the error message Failed to download or validate user artifacts appears in the Policy Response section of your Elastic Defend integration policy, you can resolve the error by adding the affected endpoint policy artifacts as global trusted applications, endpoint exceptions, event filters, blocklist entries, or host isolation exceptions.

    To find the affected endpoint policy artifacts:

    1. Go to Fleet → Agent policies.
    2. Open the impacted Elastic Agent policy.
    3. Select Actions → View policy.
    4. Search for compression_algorithm: none in the policy details. This field-value pair will appear under the affected endpoint policy artifacts.

8.7.0edit

Known issuesedit

  • After upgrading Elastic prebuilt rules, some rules are erroneously duplicated as custom rules. To remove them, go to the Rules page (Manage → Rules), click the Custom rules filter next to the search bar, then select and delete the duplicate rules.
  • After alerts are generated for the first time, you may have to refresh your browser before your alert data appears on pages that use data views (for example, Timeline). Navigating between pages will not work (#3046).

  • The Elastic Agent upgrade from 8.6.2 to 8.7.0 might fail for Elastic Agents running the Osquery Manager integration (#2433). To prevent this, delete the Osquery Manager integration from your Elastic Agents before upgrading them to 8.7.0, then re-add it after upgrading.

    If you already upgraded your Elastic Agents, and they’re are stuck in the Updating state, you’ll need to upgrade them using the API instead of Fleet. First, remove the Osquery integration from the Elastic Agents, then use the Agent upgrade API to start the upgrade. After the upgrade completes, add the Osquery Manager integration to the Elastic Agents again.

    This problem can occur when upgrading Elastic Agents from 8.6.2 or 8.7.0 to any other version. Keep this in mind when upgrading Elastic Agents running 8.6.2 or 8.7.0 to newer versions.

  • Enabling malware protection on Linux hosts might cause Elastic Defend to enter a failed state when mount points are unmounted, which will stop the integration from working. To fix this, turn off malware protection on the Elastic Defend integration policy.
  • Index aliases and some data streams are not properly retrieved by the Elastic Security default data view.
  • The Add exceptions flyout loads indefinitely and an out of memory error displays when a rule has a large number of unmapped fields in multiple indices. To avoid this issue, use the exception APIs to manage exceptions.
