Machine-written summary

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

Eclipse Vert.x (io.vertx:vertx-core) versions 3.5.0 through 3.5.3 are affected. The OpenAPI XML type validator creates XML parsers without adequate protection against XML attacks, and this applies only when a developer uses that validator to validate a supplied schema. The source does not describe the attacker's exact requirements or the impact. Upgrade to version 3.5.4 or later.
