CVE-2020-3866
Searching for and opening a file from an attacker controlled NFS mount may bypass Gatekeeper.
MEDIUM 5.5EPSS 0.68%
Does this matter?
Lower severity and a low EPSS score (0.68%). Track it; it rarely justifies an emergency change on its own.
Description
This was addressed with additional checks by Gatekeeper on files mounted through a network share. This issue is fixed in macOS Catalina 10.15.3. Searching for and opening a file from an attacker controlled NFS mount may bypass Gatekeeper.
