Machine-written summary

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

The MinIO Java Client (io.minio:minio, Maven) versions before 8.6.0 automatically substituted XML tag values that referenced system properties or environment variables with their actual values. An attacker who can supply XML content to an affected application could extract sensitive data such as credentials or system configuration. Upgrade to version 8.6.0 or later; until then, avoid parsing XML from untrusted sources.
