Revelation 0.4.13-2 and earlier uses only the first 32 characters of a password followed by a sequence of zeros, which reduces the entropy and makes it easier for context-dependent attackers to crack passwords and obtain access to keys via a brute-force attack.

Revelation 0.4.13-2 and earlier does not iterate through SHA hashing algorithms for AES encryption, which makes it easier for context-dependent attackers to guess passwords via a brute force attack.

The fpm exporter in Revelation 0.4.13-2 and earlier encrypts the version number but not the password when exporting a file, which might allow local users to obtain sensitive information.
