Name of the Vulnerable Software and Affected Versions: SharpZipLib versions prior to 1.0 RC1

Description: The issue allows attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction, also known as 'Zip-Slip'.

Recommendations: For versions prior to 1.0 RC1, update to version 1.0 RC1 or later to resolve the issue. As a temporary workaround, consider validating and sanitizing Zip archive entries to prevent directory traversal attacks. Restrict access to sensitive files and directories to minimize the risk of exploitation.
