Machine-written summary

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

Versions of the pf4j library below 3.14.1 are vulnerable to path traversal through the extract() function in Unzip.java, which does not properly handle zip entry names. An attacker who can supply a crafted zip archive for extraction could write files outside the intended directory, a Zip Slip attack. Upgrade to pf4j 3.14.1 or later.
