seems like the security plugin didnt have snapshot for 2.19.3 yet: https://central.sonatype.com/artifact/org.opensearch.plugin/opensearch-security/2.19.2.0/dependents

why do we backport it to 2.19 rather than 2.x?

Since we have already moved to 3.x era for major version release, I think the 2.19 should be the last minor version we support for future 2.x patch releases. Similar thing was also applied to 1.3 branch when we first released 2.0 - when we do the backport of 1.x changes we directly backport it to 1.3. cc @LantaoJin

Oh, sounds we had many 2.x backportings which should be backported to 2.19 instead. For example, 2.19...2.x
