Description Andrej Nemec 2018-06-27 08:54:24 UTC

A malicious server for a special remote could trick git-annex into decrypting a file that was encrypted to the user's gpg key. This attack could be used to expose encrypted data that was never stored in git-annex. Daniel Dent discovered this attack in collaboration with Joey Hess.
