XADMaster is an objective-C library for archive and file unarchiving and extraction. When extracting a specially crafted zip archive XADMaster may not apply quarantine attribute correctly. Such behaviour may circumvent Gatekeeper checks on the system. Only macOS installations are affected. This issue was fixed in XADMaster 1.10.8. It is recommended to upgrade to the latest version. There are no known workarounds for this issue.
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
