CVE-2024-38211Network attack vector

Content spoofing via unvalidated redirect targets

Published Aug 13, 2024 · Updated Jul 10, 2025

Open redirect in Microsoft Dynamics 365 (on-premises) version 9.1 before Update 1.31 allows remote attackers to spoof content via crafted links. Microsoft identifies improper redirection to an untrusted site but has not published the affected endpoint or the missing target-validation operation. Exploitation requires user interaction with attacker-supplied content; information can be exposed and displayed content altered, with no reported service interruption.
