ServiceNow AI Platform patches five access flaws
Free public brief. The indicators, the detections with Splunk and KQL already written, and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
CIS advisory details five ServiceNow AI Platform vulnerabilities, including SQLi and auth bypass, that could let attackers access or modify data without authorization.
CIS/MS-ISAC issued an advisory covering five vulnerabilities in ServiceNow's AI Platform affecting Yokohama, Zurich, and Australia release lines prior to specific patch/hotfix levels. The flaws span authorization bypass, improper access control, missing authorization, and a SQL injection vulnerability. The most severe issues could allow unauthenticated attackers to create, modify, or delete instance data, execute arbitrary SQL against the underlying database, or extract data beyond intended access, potentially leading to privilege escalation. One flaw (CVE-2026-86857) requires authentication, while the others (CVE-2026-86858, CVE-2026-13016, CVE-2026-86859, CVE-2026-86860) can be exploited without authentication in certain circumstances.
There are no current reports of in-the-wild exploitation. ServiceNow has already remediated these issues, and the advisory maps the risk to MITRE ATT&CK's Exploit Public-Facing Application (T1190) technique under Initial Access. Defenders running affected ServiceNow versions should prioritize patching to the specified hotfix levels and apply standard vulnerability management practices, including patch automation, vulnerability scanning, network segmentation, and least-privilege enforcement, as outlined in the CIS Safeguards referenced in the bulletin.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections with the Splunk SPL and Microsoft KQL already written, the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 10,217 reports from 155 sources, 1,839 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
