CVE-2018-20211
ExifTool 8.32 allows local users to gain privileges by creating a %TEMP%\par-%username%\cache-exiftool-8.32 folder with a victim's username, and then copying a Trojan horse ws32_32.dll file into this new folder, aka DLL Hijacking.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
