Elasticsearch version 7.10.2edit

Also see Breaking changes in 7.10.

Security updatesedit

  • An information disclosure flaw was found in the Elasticsearch async search API. Users who execute an async search will store the HTTP headers. A user with the ability to read the .tasks index could obtain sensitive request headers of other users in the cluster. All versions of Elasticsearch between 7.7.0 and 7.10.1 are affected by this flaw. You must upgrade to Elasticsearch version 7.10.2 to obtain the fix. CVE-2021-22132

Known issuesedit

  • Snapshot and restore: If an index is deleted while the cluster is concurrently taking more than one snapshot then there is a risk that one of the snapshots may never complete and also that some shard data may be lost from the repository, causing future restore operations to fail. To mitigate this problem, prevent concurrent snapshot operations by setting snapshot.max_concurrent_operations: 1.

    This issue is fixed in Elasticsearch versions 7.13.1 and later. For more details, see #73456.
