Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Elasticsearch's x-pack-security Maven package (org.elasticsearch.plugin:x-pack-security) is affected in versions before 8.19.9, from 9.0.0 before 9.1.9, and from 9.2.0 before 9.2.3. An authenticated user with low privileges can submit oversized user settings data, causing excessive memory allocation that crashes the node with an out-of-memory error, a persistent denial of service. Upgrade to 8.19.9, 9.1.9, or 9.2.3.
