Machine-written summary

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

OpenDJ's opendj-dsml-servlet component (Maven opendj-dsml-servlet from org.openidentityplatform.opendj) is vulnerable in versions before 5.1.2. An unauthenticated remote attacker can send a DSMLv2 request containing a URI value, which the server fetches, allowing server-side request forgery to internal services, reading local files, and memory exhaustion through unbounded reads. Upgrade to version 5.1.2, which disables URI dereferencing by default and requires authentication for the gateway.
