CVE-2026-47646 is a critical cross-site scripting vulnerability in Microsoft Dynamics 365 Customer Voice. The flaw is caused by improper neutralization of attacker-controlled input during web page generation in the Customer Voice survey rendering and handler functionality. A maliciously crafted survey link can cause script to execute in the context of a victim’s authenticated Dynamics 365 Customer Voice session when the victim opens the link. The issue is exploitable over the network without authentication, but requires user interaction. Because the injected script runs in the victim’s browser within the trusted application context, the vulnerability can be used for spoofing and broader session-level compromise actions against the affected cloud service.
