Feiten: Microsoft heeft kwetsbaarheden verholpen in Dynamics, zowel online als on-premise.

Interpretaties: De kwetsbaarheden stellen een kwaadwillende in staat om zich verhoogde rechten toe te kennen, willekeurige code uit te voeren en/of toegang te krijgen tot gevoelige gegevens. De ernstigste kwetsbaarheid heeft kenmerk **CVE-2026-59118** toegewezen gekregen en bevindt zich in Power Apps. Deze kwetsbaarheid is echter reeds door Microsoft zelf centraal verholpen en slechts opgenomen ter informatie. Voor deze kwetsbaarheid is geen actie (meer) vereist.

Oplossingen: Microsoft heeft updates beschikbaar gesteld waarmee de beschreven kwetsbaarheden worden verholpen. We raden u aan om deze updates te installeren. Meer informatie over de kwetsbaarheden, de installatie van de updates en eventuele work-arounds vindt u op: https://portal.msrc.microsoft.com/en-us/security-guidance
