Official Description
Vtiger CRM 8.4.0 contains a reflected cross-site scripting (XSS) vulnerability in the MailManager module. Improper handling of user-controlled input in the _folder parameter allows a specially crafted, double URL-encoded payload to be reflected and executed in the context of an authenticated user s session.
Technical Analysis
CVE-2025-70936 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
