Affected versions of this package are vulnerable to Improper Input Validation. The Verifiable Secret Sharing scheme generates shares from the user’s IDs but does not properly validate them. Using a malicious ID will make other users reveal their secrets during the secret-sharing procedure. In addition, a second issue resulting from lack of validation could cause nodes to crash when sent maliciously formed user IDs.
