CVE-2018-1002209
QuaZIP before 0.7.6 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction.
Does this matter?
Lower severity and a low EPSS score (5.47%). Track it; it rarely justifies an emergency change on its own.
Description
