Description

WAL-G before 1.1, when a non-libsodium build (e.g., one of the official binary releases published as GitHub Releases) is used, silently ignores the libsodium encryption key and uploads cleartext backups. This is arguably a Principle of Least Surprise violation because "the user likely wanted to encrypt all file activity."
