Vulnerability from github – Published: 2026-01-05 15:32 – Updated: 2026-01-05 23:14Improper Restriction of XML External Entity Reference vulnerability in Apache SIS.
It is possible to write XML files in such a way that, when parsed by Apache SIS, an XML file reveals to the attacker the content of a local file on the server running Apache SIS. This vulnerability impacts the following SIS services:
-
Reading of GeoTIFF files having the GEO_METADATA tag defined by the Defense Geospatial Information Working Group (DGIWG).
-
Parsing of ISO 19115 metadata in XML format.
-
Parsing of Coordinate Reference Systems defined in the GML format.
-
Parsing of files in GPS Exchange Format (GPX).
This issue affects Apache SIS from versions 0.4 through 1.5 inclusive. Users are recommended to upgrade to version 1.6, which will fix the issue. In the meantime, the security vulnerability can be avoided by launching Java with the javax.xml.accessExternalDTD system property sets to a comma-separated list of authorized protocols. For example:
java -Djavax.xml.accessExternalDTD="" ...

Mitigation
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
