High (7.5). EPSS 1.0% chance of exploitation in the next 30 days. Fixed in diffoscope 256.
diffoscope before 256 allows directory traversal via an embedded filename in a GPG file. Contents of any file, such as ../.ssh/id_rsa, may be disclosed to an attacker. This occurs because the value of the gpg --use-embedded-filenames option is trusted.
