CVE-2024-38166 is a cross-site scripting vulnerability in Microsoft Dynamics 365 caused by improper neutralization of untrusted input during web page generation. The flaw allows an unauthenticated attacker to craft malicious web content or a specially prepared link that, when opened by a target user, triggers script execution in the context of the affected Dynamics 365 application. The vulnerability is described as enabling spoofing over a network and is consistent with reflected or link-delivered XSS behavior requiring user interaction.
