ServiceNow customers were urged to patch multiple critical remote code execution vulnerabilities after reports that flaws in the platform were being actively exploited. One set of bugs affected core ServiceNow deployments and was serious enough to trigger immediate warnings from security researchers and industry media, highlighting the risk of unauthenticated or low-friction compromise in widely used enterprise workflow environments.
A separate report later identified another critical RCE vulnerability in the ServiceNow AI Platform, expanding concern from the core platform to newer AI-enabled components. Together, the disclosures indicate that attackers have had viable paths to execute code against ServiceNow environments across both traditional and AI-related services, raising the stakes for organizations that use the platform for IT, HR, security, and business process automation.

ServiceNow disclosed and remediated **CVE-2026-6875**, a critical sandbox escape in its AI Platform that can allow **unauthenticated remote code execution** in certain circumstances. The vulnerability affects both hosted and self-hosted ServiceNow environments, carries a **CVSS 4.0 score of 9.5**, and was published in advisory `KB3137947`. ServiceNow said it has already deployed security updates to hosted instances and issued patched family releases and updates for self-hosted customers and partners. The company said it is **not currently aware of active exploitation**, but warned that successful compromise could let attackers execute code within the ServiceNow platform, disrupt workflows, access sensitive data, modify records, and enable follow-on malicious activity. To reduce near-term exploit risk, ServiceNow limited public technical details while directing customers to promptly apply the relevant updates or upgrade to patched releases, including fixes for the **Brazil, Australia, Zurich, and Yokohama** release families.

ServiceNow patched a **critical unauthenticated remote code execution (RCE)** vulnerability in the *ServiceNow AI Platform* tracked as **CVE-2026-0542**. The flaw can allow an unauthenticated attacker, under certain conditions, to execute code within the **ServiceNow Sandbox**—a restricted environment intended to isolate untrusted code—creating risk of broader instance compromise, including potential data theft and workflow manipulation. Public technical details were limited, but the issue was characterized as remotely reachable (typically over HTTPS) and high impact, with reporting citing **critical severity (CVSS 9.8)**. ServiceNow’s advisory (**KB2693566**) states the company deployed security updates to affected **hosted customer instances** and also made updates available to **self-hosted customers and partners** via patches/hotfixes. As of the advisory information reflected in CVE tracking, ServiceNow reported it was **not aware of active exploitation against customer instances**, but recommended customers apply the relevant updates or upgrade promptly to mitigate the risk from an unauthenticated RCE path into the sandboxed execution environment.

ServiceNow disclosed and remediated a **critical** vulnerability in its AI Platform, tracked as **CVE-2025-12420** (CVSS **9.3**), that could allow an **unauthenticated attacker to impersonate legitimate users** and perform actions with the victim’s entitlements. The issue impacts ServiceNow AI features including **Now Assist AI Agents** and the **Virtual Agent API**; ServiceNow reported deploying fixes to most hosted instances in October 2025 and providing updates to partners and self-hosted customers, and stated it has **no evidence of exploitation** prior to remediation. Research associated with the disclosure highlighted broader risks in enterprise AI agent deployments, including the potential for **second-order prompt injection** when default settings and agent-to-agent capabilities (e.g., *agent discovery*) are not tightly controlled. In testing described by the reporting, low-privileged users could embed malicious instructions into data fields later processed by higher-privileged AI agents, potentially leading to unauthorized access or changes; customers were advised to upgrade to patched releases (including *Now Assist AI Agents* `5.1.18+` / `5.2.19+` and *Virtual Agent API* `3.15.2+` / `4.0.4+`) and to apply relevant security updates across hosted and self-managed environments.
