Summary

MPXJ is an open source library to read and write project plans from various file formats and databases. From 7.3.0 until 16.5.0, reading a crafted Primavera P3 PRX or SureTrak STX file can cause MPXJ to write files to arbitrary locations in the filesystem. Fixed in version 16.5.0.

Risk Assessment

An attacker could exploit this to overwrite or create files on the system, potentially leading to data corruption or persistent access.

Recommendation

Upgrade MPXJ to version 16.5.0 or later.

Other vulnerabilities in MPXJ

CVE-2026-61570High
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.
