    Insufficient Entropy

    pubnub is a Publish & Subscribe Real-time Messaging with PubNub

    Affected versions of this package are vulnerable to Insufficient Entropy via the getKey function, due to inefficient implementation of the AES-256-CBC cryptographic algorithm. The provided encrypt function is less secure when hex encoding and trimming are applied, leaving half of the bits in the key always the same for every encoded message or file.

    Note:

    In order to exploit this vulnerability, the attacker needs to invest resources in preparing the attack and brute-force the encryption.

    How to fix Insufficient Entropy?

    Upgrade pubnub to version 7.4.0 or higher.
