Cloud technology giant ServiceNow has notified some of its enterprise customers that a software bug on its platform was allowing anyone on the internet to access their data.
What Happened
A knowledge base article, which ServiceNow has hidden behind a login wall but has been shared on Reddit, says the company on June 5 patched some customer instances to fix a bug that had allowed unauthenticated users to “gain greater access” to ServiceNow-hosted data than intended.
The bug allowed potentially anyone to access data stored in customer instances without requiring credentials, such as a password. On June 5, 2026, ServiceNow applied a security update that concerned a security issue that could allow an unauthenticated user, in certain circumstances, to gain greater access to ServiceNow instances than intended.
According to the knowledge base article, the company has taken steps to provide this security update to partners and customers. The post on Reddit also shared an FAQ published by the company, which includes questions such as "Is my instance in scope of the security issue?" and "Will additional actions be required later?"
Background and Context
ServiceNow is a cloud computing giant that allows thousands of its enterprise customers to automate their internal business processes. Companies use the tech giant’s platform to build workflows that connect to various apps and databases, such as IT and HR systems, which can be used to automatically handle repeat tasks, like onboarding staff, resolving tech support tickets, and for chatbots.
As such, companies like ServiceNow can be high-value targets for hackers thanks to the amount of sensitive data that they store, such as customer support tickets, which can include passwords, keys, and credentials. The company hosts workflow, IT management, human resources, and customer-service systems for thousands of organizations worldwide, making it a significant repository of sensitive corporate information.
According to reports citing a customer advisory, the flaw involved an API endpoint that lacked proper authentication controls. Security researchers and cybersecurity analysts said the vulnerability could have allowed attackers to query information stored in affected customer environments, potentially including internal documentation, support tickets, employee records, workflow data, and configuration details.
Why it Matters
The incident highlights the importance of securing application programming interfaces, or APIs, which increasingly act as gateways between enterprise systems and cloud-based services. Several reports indicate evidence of exploitation occurred before the company issued its patch, though the scope of the activity remains unclear.
Cybersecurity researchers said the issue underscores the need for robust security measures to protect against unauthorized access to sensitive corporate information. The incident also arrives as software vendors are facing increased scrutiny over cloud security practices, with organizations centralizing critical business operations on software platforms.
What Comes Next
ServiceNow has reportedly contacted impacted customers directly and advised organizations to review logs for suspicious activity. While the company has not publicly disclosed how many customers were affected or what specific data may have been accessed, the incident serves as a reminder of the importance of robust security measures in protecting against unauthorized access to sensitive corporate information.
