An issue was discovered in io/gpx/GPXDocumentReader.java in TuxGuitar 1.5.4. It uses misconfigured XML parsers, leading to XXE while loading GP6 (.gpx) and GP7 (.gp) tablature files.
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
