deprecated elasticsearch plugin 2.4.5

[christiangierschner]

Hi...

recently there was a elasticsearch CVE...i then checked all elasticsearch occurences in our environment and found a very very old elasticsearch version (2.4.5) in our recent OPAL server (4.5.8)

in your installation docs you say:
Because having a search engine is an absolute requirement, Opal server will check at startup that there is a plugin of type opal-search and if it’s not the case, the latest version of the [opal-search-es](https://github.com/obiba/opal-search-es/releases) plugin (that applies to the current Opal server version) will be automatically downloaded and installed without needing a server restart. If for any reason this plugin cannot be automatically downloaded (network issue), the Opal start-up will fail and you will need to install the plugin manually.

this is the line from your Dockerfile in which you install opal-search-es

The Plugin itself was last updated 2 years ago...

Could you please update all of your plugins to the most recent safe-to-use versions because of the requirement that a deprecated search plugin has to be installed in the server deployment...

Or remove the opal-search-es dependency...

Yes we know that... The problem is that since ES5 (that just followed 2.4), ES could not be embedded in a java application anymore. We could have done like with Mica: abstract the ES API and make a plugin for higher versions of ES but some of the search features opal is using have been removed. There is quite some refactoring work then.

so, remove the automatic install and the dependency or does opal just not work without opel-search-es?

You can stop the search service, and verify how opal behaves.
