Description

This module exploits an XML External Entity (XXE) vulnerability in GeoServer
via the WMS GetMap operation. The vulnerability allows reading arbitrary files
from the server's file system by injecting an XXE entity in the SLD (Styled Layer Descriptor).

Affected versions:
- GeoServer >= 2.26.0,
- GeoServer

The file content is returned in the error message when the layer name contains
the XXE entity reference.
