Summary

The FluentCRM plugin for WordPress is susceptible to unauthorized data modification, allowing unauthenticated attackers to manipulate user subscriptions. This vulnerability arises from the insecure implementation of MD5 hashing without a salt used for managing subscriptions. As a result, if attackers gain access to a targeted subscriber's email address, they can unsubscribe users from lists and change subscription settings, undermining the integrity of user data and trust in the platform.

Affected Version(s)

Email Marketing, Newsletter, Email Automation and CRM Plugin for WordPress by FluentCRM 2.7.40

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
