ServiceNow has remediated an authorization bypass security issue that was identified in the ServiceNow AI Platform. This security issue, if exploited, could enable an authenticated user to access data within the ServiceNow AI Platform that the user otherwise would not be entitled to access, potentially enabling further unintended access. ServiceNow deployed an update to hosted instances, and ServiceNow provided the update to our partners and self-hosted customers. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.
