A fix is available — apply it.

A remote code execution vulnerability exists in Microsoft Dynamics 365 (on-premises) when the server fails to properly sanitize web requests to an affected Dynamics server. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SQL service account. An authenticated attacker could exploit this vulnerability by sending a specially crafted request to a vulnerable Dynamics server. The security update addresses the vulnerability by correcting how Microsoft Dynamics 365 (on-premises) validates and sanitizes user input.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
