CWE-250Published: May 12, 2026· Updated: May 14, 2026
Official Description
Execution with unnecessary privileges in Microsoft Dynamics 365 (on-premises) allows an authorized attacker to execute code over a network.
Technical Analysis
CVE-2026-42833 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
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.
