Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache SIS (Maven package org.apache.sis.core:sis-metadata) versions 0.4 through 1.5 are vulnerable to XML external entity injection when parsing GeoTIFF files with DGIWG GEO_METADATA tags, ISO 19115 XML metadata, GML coordinate reference systems, or GPX files. An attacker who can supply such a file can read the contents of local files on the server. Upgrade to version 1.6, which fixes the issue. As a workaround, set the javax.xml.accessExternalDTD system property to restrict external protocols when launching Java.
