Good job everyone! Today, secret agent semchapeu requests you to evaluate the security of a project codenamed "Strip Me"

Found a real vulnerability while playing 2021 Advent OverTheWire.org! If you use Exiftool, you should update to 12.38 or above. Full details are in my write-up for the day 8 challenge “Strip Me!” by semchapeu : joe.lothan.net/ctfs/2021-adve…
