Machine-written summary

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

The Elastic APM Java agent packages apm-agent-parent and elastic-apm-agent, versions 1.18.0 up to but not including 1.27.1, are affected. A local user on the system can attach a malicious plugin to an application running the agent, which lets them execute code with higher permissions than their account normally has. Upgrade both packages to 1.27.1.
