Scripts from untrusted sources will be blocked, with major impact on SPFx solutions using external scripts or inline JavaScript.\n\n* * *\n\nℹ️\n\n**Key Facts:**\n\n* * *\n\nOrganizations should review CSP violations in Microsoft Purview Audit logs and add trusted script sources in SharePoint Admin Center (Advanced → Script sources) before enforcement begins. Inline scripts must be refactored to external files – this requires updating the SPFx solution.\n\n**Sources:** MC1193419 · Microsoft Learn",
