ServiceNow patched four flaws in its widely used AI Platform, three of them scored 10.0 and exploitable by an unauthenticated attacker with no user interaction. The first, CVE-2026-18885, is a code injection in the GraphQL Composite Data API that allows arbitrary code execution and access to instance data. The second, CVE-2026-18886, is an access-control flaw in the configuration image-upload processor that lets an attacker create or modify data and escalate privileges. The third, CVE-2026-74820, is a SQL injection allowing arbitrary queries against the instance database. ServiceNow fixed hosted instances itself, but self-managed customers must apply the updates. No exploitation of these three has been reported yet.
Researchers at Reco detailed a long-running data-theft campaign they call City-Forum that has been quietly stealing records from Salesforce and ServiceNow customer portals since at least March 2025. Rather than exploiting a platform vulnerability, the attacker uses custom tooling to pull data that organizations mistakenly exposed to anonymous guest users through overly permissive sharing rules and portal settings. It targets Salesforce Experience Cloud sites and a poorly documented ServiceNow portal search endpoint, hitting telecoms, banks, software vendors, security firms, and public-sector portals worldwide. All activity traces to a single server, and one victim alone saw over half a million data enumeration requests.
A critical flaw in the ServiceNow AI Platform is now being exploited in attacks. ServiceNow disclosed CVE-2026-6875 on July 13 in advisory KB3137947, describing it as a sandbox escape that lets an attacker bypass intended platform restrictions and execute code, and noting that exploitation does not require authentication. The AI Platform underpins much of the company's IT service management and workflow tooling, and the flaw affects both hosted and self-hosted deployments. ServiceNow deployed fixes to its hosted instances and released updates for self-hosted customers. Because these instances commonly connect to identity systems, cloud services, and endpoint management tools, a compromised one is a strong pivot point.
ServiceNow has quietly told affected customers that attackers exploited an unauthenticated flaw in one of its API endpoints to pull data from hosted customer instances. The company applied a fix to hosted instances on June 5 that restricts the endpoint to authenticated users, and confirmed attackers had successfully queried customer instance tables, though it did not say what data was taken. ServiceNow instances routinely hold sensitive material such as IT support tickets, employee records, asset inventories, and internal documentation, and support tickets in particular often contain credentials, API tokens, and secrets shared during troubleshooting. ServiceNow has opened support cases with the customers it believes were impacted.
