6.5MEDIUM

What is CVE-2023-1430?

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)

FluentCRM – Email Newsletter, Automation, Email Marketing, Email Campaigns, Optins, Leads, and CRM Solution 0 <= 2.8.0.1

Exploit Proof of Concept (PoC)
