Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The jersey-core package (Maven com.sun.jersey:jersey-core) is affected in versions before 1.13. The source describes an XML external entity (XXE) issue in which parameter entities are not disabled by the Jersey SAX parser, so processing crafted XML can lead to unintended file access or data disclosure; the source gives few further details about the attack conditions. Upgrade to jersey-core 1.13 or later.
