Medium (4.4) in netflix hollow. EPSS 0.3% chance of exploitation in the next 30 days.
In Netflix OSS Hollow, since the Files.exists(parent) is run before creating the directories, an attacker can pre-create these directories with wide permissions. Additionally, since an insecure source of randomness is used, the file names to be created can be deterministically calculated.
