Support for using Elasticsearch 7.17.13 with Bitbucket Server & Data Center should be added.
Due to a known issue “Elasticsearch uncontrolled resource consumption (ESA-2023-13)” with Elastic Search, the following ElasticSearch versions are affected: Elasticsearch versions up to 7.17.12 and from 8.0.0 up to 8.8.2
To resolve this issue with Elasticsearch, it is advised to upgrade to Elasticsearch version 7.17.13 and 8.9.0 and higher.
As we already have a feature request for ElasticSearch 8.x support (BSERV-13247), requesting to provide support for ES version 7.17.13
Current Supported Versions: From the Bitbucket Support Document
We can see that Bitbucket 8.9.x supports - 7.17.6 (Maximum)
And Bitbucket 8.14.x version supports - ElasticSearch version 7.17.10 (maximum)
