Machine-written summary

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

commons-jelly versions before 1.0.1 are vulnerable to XML external entity (XXE) attacks. An attacker who can get a crafted Jelly file parsed can make the parser connect to a URL of their choice by declaring a custom SYSTEM entity and using it in the file body. Upgrade to commons-jelly 1.0.1 or later.
