Critical ServiceNow Vulnerability Lets Remote Attackers Execute Code

Key Takeaways

• ServiceNow has patched a critical vulnerability, CVE-2026-6875, in its AI Platform.
• The flaw allows unauthenticated remote code execution (RCE) and affects both cloud-hosted and self-hosted ServiceNow instances.
• Successful exploitation could lead to data compromise, workflow disruption, and further network infiltration.
• Patches are available across various ServiceNow releases, and immediate application is strongly recommended.

Critical Flaw Discovered in ServiceNow AI Platform

ServiceNow has identified and subsequently patched a severe security vulnerability within its widely adopted AI Platform. This critical flaw, designated as CVE-2026-6875, could enable unauthenticated attackers to execute arbitrary code remotely on affected ServiceNow environments.

Described as a sandbox escape vulnerability, CVE-2026-6875 impacts all deployments of ServiceNow, whether they are hosted in the cloud by ServiceNow itself or managed on-premises by customers. The nature of this vulnerability allows an attacker to bypass the platform’s inherent security restrictions, potentially leading to unauthorized code execution under specific conditions.

Given that no authentication is required for exploitation, this issue presents a significant risk to any exposed ServiceNow instance that has not yet received the necessary security updates. ServiceNow’s platform is extensively utilized by enterprises globally for critical functions such as IT service management, workflow automation, customer operations, and security operations, making any compromise potentially far-reaching.

A successful remote code execution attack against such a foundational platform could grant attackers the ability to disrupt essential business processes, access sensitive corporate data, alter critical records, or leverage the compromised environment as a staging ground for more extensive network breaches.

Details of the ServiceNow Vulnerability

While the vulnerability resides within the ServiceNow AI Platform, the company has opted not to disclose detailed technical specifics regarding its underlying cause. ServiceNow published the advisory as KB3137947 on July 13, 2026. This limited disclosure strategy is typical for critical vulnerabilities, aiming to provide customers with sufficient time to apply patches before malicious actors can develop reliable exploit code.

ServiceNow has already deployed the necessary security updates to all its hosted instances. Concurrently, the company has made these critical updates available to its self-hosted customers and partners. Organizations managing their own ServiceNow environments are strongly advised to review their current release family and promptly install the appropriate patch or upgrade to a fixed version.

Specific patches have been released across various ServiceNow versions: the issue is resolved in Brazil Early Access and Brazil General Availability releases. For Australia, the vulnerability is addressed in Australia Patch 2. Zurich customers should install Zurich Patch 7b or Zurich Patch 9. Yokohama users are protected by Yokohama Patch 12 Hot Fix 1b or Yokohama Patch 13.

ServiceNow has stated that it is currently unaware of any active exploitation of CVE-2026-6875 in the wild. However, the public disclosure of a critical, unauthenticated remote code execution flaw often quickly attracts the attention of both legitimate security researchers and malicious actors. Consequently, organizations should treat this issue with urgency, even if they have not yet observed any suspicious activity.

What You Should Do

• Identify Deployment Type: Determine whether your ServiceNow instance is hosted by ServiceNow or deployed in a self-hosted environment.
• Verify Hosted Updates: If your instance is hosted by ServiceNow, confirm that the platform update has been applied.
• Patch Self-Hosted Instances: For self-hosted environments, review ServiceNow’s security maintenance guidance (KB2930717 and KB2930740) and install the relevant patch or upgrade to a fixed version immediately.
• Monitor for Anomalies: Security teams should monitor for unusual administrative activity, unexpected workflow modifications, suspicious API behavior, and any unusual integrations following the update.
• Prioritize Remediation: Treat this vulnerability as urgent. Prompt remediation remains the most effective defense against potential exploitation.
