CVE-2026-61570
Published:September 22, 2026
Updated:October 12, 2026
MPXJ is an open source library to read and write project plans from a variety of file formats and databases. From 5.5.5 until 16.4.1, MerlinReader creates a DocumentBuilder with default settings while parsing XML from the ZTIMEINTERVALS column of a Merlin project SQLite database, leaving doctype declarations and external entities enabled. A crafted database can cause the parser to read an arbitrary local file, although MPXJ's subsequent handling of the parsed XML makes disclosure of the file contents unlikely. This issue is fixed in version 16.4.1.
