Machine-written summary

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

MPXJ, a library for reading project planning files, is vulnerable to path traversal in versions 8.3.5 up to but not including 13.5.1, across its Maven, RubyGems, PyPI and NuGet packages. The source says an incomplete earlier fix for CVE-2020-35460 leaves a malicious path that can write files to arbitrary locations. Upgrade to version 13.5.1; the source's workaround is to avoid passing zip files to MPXJ.
