Name of the Vulnerable Software and Affected Versions: DotNetZip.Semvered versions prior to 1.11.0

Description: The issue allows attackers to perform directory traversal, enabling them to write to arbitrary files. This is achieved by including a ../ (dot dot slash) in a Zip archive entry, which is mishandled during extraction. The issue is also referred to as 'Zip-Slip'.

Recommendations: For versions prior to 1.11.0, update to version 1.11.0 or later to resolve the issue. As a temporary workaround, consider validating and sanitizing Zip archive entries to prevent the inclusion of ../ (dot dot slash) sequences during extraction.
