Enterprise automation platforms are critical for streamlining workflows, but they can also become targets for attackers. ServiceNow recently disclosed a critical vulnerability in its AI Platform that allows unauthenticated attackers to remotely execute code within the Sandbox environment.
Although exploitation in the wild has not been observed, this vulnerability poses a serious risk to enterprise workflow data, automation logic, and integrated systems. This article provides a detailed breakdown of the threat, affected versions, and actionable mitigation steps for IT managers, security teams, and enterprise decision-makers.
Overview of the Vulnerability
CVE-2026-0542, documented in ServiceNow’s advisory KB2693566, is classified as critical.
| Field | Details |
|---|---|
| CVE ID | CVE-2026-0542 |
| Advisory ID | KB2693566 |
| Severity | Critical |
| Attack Type | Remote Code Execution (RCE) |
| Authentication Required | No (Unauthenticated) |
| Affected Product | ServiceNow AI Platform |
| Exploitation in the Wild | Not detected |
| Advisory Published | February 25, 2026 |
How the Exploit Works
The vulnerability resides within the ServiceNow AI Platform Sandbox, allowing an unauthenticated attacker to execute arbitrary code remotely. Potential consequences include:
- Exposure of sensitive workflow and automation logic
- Compromise of enterprise integrations managed through ServiceNow
- Unauthorized access to sandbox data and experimental AI processes
Key insight: Even though the attack surface is limited to the Sandbox, organizations relying on integrated workflows and external connections should treat this as a high-priority threat.

- Hosted customer instances received updates as of January 6, 2026
- Self-hosted deployments and partners should verify patch installation
- Organizations with internet-accessible or externally integrated instances must prioritize updates
Pro tip: Customers who participated in the January 2026 Patching Program already received the updates. If you did not receive a notification, your instance may be unaffected—but verification is essential.
Risk Impact for Enterprises
- Remote Code Execution (RCE): Allows attackers to manipulate AI workflows or inject malicious scripts.
- Data Exposure: Sensitive business logic and automation rules could be compromised.
- Integration Risk: Connected systems and third-party APIs may become secondary targets if the Sandbox is exploited.
- Operational Disruption: Exploitation could interrupt testing or experimental AI processes critical to enterprise operations.
Expert insight: Even without observed exploitation in the wild, critical RCE vulnerabilities in SaaS platforms require immediate remediation, especially in integrated or internet-facing deployments.
Recommended Mitigation Steps
Immediate Actions
- Verify Current Release: Check your ServiceNow release version and ensure it matches the patched builds.
- Apply Patches: Deploy the fixed versions listed above for your instance.
- Review Integrations: Audit connected systems for potential exposure.
Enterprise Measures
- Restrict Sandbox Access: Limit external connections to Sandbox environments.
- Monitor Logs: Track unusual activity in the AI Platform, including script execution and workflow changes.
- Coordinate with IT and Security Teams: Ensure incident response plans include potential RCE incidents in SaaS platforms.
Tools and Frameworks to Support Detection
- ServiceNow Security Advisory Portal: Monitor new vulnerabilities and patch updates.
- NIST CVE Database: Track updates for CVE-2026-0542.
- MITRE ATT&CK: Map potential lateral movement or exploitation in enterprise environments.
- SIEM/Monitoring Tools: Watch for anomalous script execution or suspicious API calls.
Pro tip: Combine patch management with continuous monitoring to prevent potential exploitation and maintain compliance.
