Critical ServiceNow Vulnerability Alert: What Australian Businesses Need to Know in 2026
A critical ServiceNow vulnerability is now being actively exploited by threat actors, putting thousands of organisations at immediate risk of remote code execution attacks. First disclosed earlier this year, CVE-2026-6875 has escalated from a theoretical concern to a real-world threat, with threat intelligence firm Defused confirming active exploitation campaigns targeting the ServiceNow AI Platform across multiple industries.
For Australian businesses relying on ServiceNow for IT service management, this vulnerability demands urgent attention. The flaw carries a CVSS score of 9.8, classifying it as critical severity, and requires no authentication to exploit—making it particularly dangerous for internet-facing deployments.

What Happened: ServiceNow CVE-2026-6875 Exploitation Timeline
The critical ServiceNow vulnerability was initially discovered by security researchers in early 2026, with ServiceNow releasing patches shortly after responsible disclosure. However, many organisations delayed applying updates, leaving their systems exposed.
According to Defused’s threat intelligence report, attackers began weaponising the vulnerability in mid-July 2026. The exploitation activity shows hallmarks of organised cybercriminal groups, with evidence suggesting both opportunistic scanning and targeted attacks against high-value organisations.
Key Timeline Events
- Q1 2026: Vulnerability discovered and reported to ServiceNow
- Q2 2026: Security patches released for affected versions
- July 2026: Proof-of-concept exploit code appears on underground forums
- July 20, 2026: Active exploitation confirmed by Defused
How Does the ServiceNow Code Execution Attack Work?
The vulnerability exists within the ServiceNow AI Platform’s input validation mechanisms. Attackers can craft malicious requests that bypass security controls, ultimately achieving remote code execution (RCE) on vulnerable systems.
What makes this flaw particularly severe is its pre-authentication nature. Threat actors don’t need valid credentials to exploit the vulnerability—they simply need network access to the ServiceNow instance.
Technical Attack Vector
- Attacker identifies internet-exposed ServiceNow instances using automated scanning tools
- Malicious payload is crafted to exploit the input validation flaw in the AI Platform component
- Successful exploitation grants the attacker arbitrary code execution privileges
- Post-exploitation activities may include data exfiltration, ransomware deployment, or lateral movement
Security researchers have noted that exploitation attempts are originating from multiple IP ranges, indicating widespread adoption of the attack technique among threat actor groups.
Business Impact: Why Australian Organisations Are at Risk
ServiceNow is extensively deployed across Australian enterprises, government agencies, and critical infrastructure providers. The platform often contains sensitive data including employee records, financial information, and operational workflows.
A successful attack exploiting this critical ServiceNow vulnerability could result in:
- Data breaches: Exposure of sensitive customer and employee information
- Operational disruption: Complete compromise of IT service management capabilities
- Regulatory penalties: Potential violations of the Privacy Act 1988 and Notifiable Data Breaches scheme
- Ransomware attacks: Attackers using initial access to deploy encryption malware
- Supply chain compromise: Lateral movement to connected systems and partner networks
The Australian Cyber Security Centre (ACSC) has historically issued alerts for similar critical vulnerabilities. Organisations should monitor ACSC advisories for official Australian government guidance on this threat.
Actionable Recommendations to Protect Your Organisation
Immediate action is essential to mitigate the risk posed by CVE-2026-6875. Our security team recommends the following steps:
Immediate Actions (Within 24-48 Hours)
- Apply patches immediately: Update all ServiceNow instances to the latest patched versions
