Machine-written summary

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

Checkstyle (Maven com.puppycrawl.tools:checkstyle) versions before 8.29 are vulnerable to XML external entity (XXE) processing, because an earlier fix for CVE-2019-9658 was incomplete. An attacker who can supply untrusted Checkstyle XML configuration files could exploit this, and the source states that Maven and Gradle builds are probably not affected. Upgrade to version 8.29 or later; the source lists no workaround.
