How to fix?

Upgrade openssl-encrypt to version 1.4.0 or higher.

Overview

openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the use of an in-memory defaultdict for rate limiting in the TOTP authentication. An attacker can bypass rate limiting by distributing authentication attempts across multiple server instances or by restarting the server to reset the rate limit state.
