Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

MPXJ versions 7.3.0 up to 16.5.0 (including the NuGet, RubyGems, PyPI and Maven packages of the same name) can write files to arbitrary locations when reading a specially crafted Primavera P3 PRX or SureTrak STX file. An attacker would need to supply such a file for the application to read, so the risk comes from opening files from untrusted sources. Upgrade to version 16.5.0 or later; until then, do not read PRX or STX files from untrusted sources.
