Machine-written summary

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

Several Eclipse Platform and JDT packages parse XML project files such as ".project" without guarding against XML external entity (XXE) attacks. A user who opens a malicious project, or updates an open project with a crafted XML file, can have the IDE process hostile XML entities. The fixed versions are org.eclipse.core.runtime 3.29.0, org.eclipse.platform 4.29.0, org.eclipse.jface 3.31.0, org.eclipse.ui.forms 3.13.0, org.eclipse.ui.ide 3.21.100, org.eclipse.ui.workbench 3.130.0, org.eclipse.urischeme 1.3.100, and org.eclipse.jdt.ui 3.30.0, so upgrade to these. No workaround is listed.
