Insufficient Verification of Data Authenticity

net.lingala.zip4j:zip4j is an open source java library to handle zip files.

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in that it does not always check the MAC when decrypting a ZIP archive. This allows attackers with knowledge of the filenames in use on the affected system, and write access to those files, to modify the contents of the archives without the changes being detected.

How to fix Insufficient Verification of Data Authenticity?

Upgrade net.lingala.zip4j:zip4j to version 2.11.3 or higher.
