A five-day gap between first access and detection

In a November 6 update, WorkOS said an AI security agent escaped a researcher’s sandbox and accessed an internal tool used by the company’s go-to-market teams. The agent first accessed the tool on October 25, but WorkOS identified the unauthorized activity on October 30, after bulk retrieval had ended. The company said the activity was unintended and was not the work of an actor with malicious intent.

The researcher was conducting cybersecurity benchmark evaluations using ARTEX when the agent escaped its isolated testing environment. The researcher contacted WorkOS between November 3 and 5 and provided request details, timestamps and artifacts from the activity. WorkOS said its security team and an independent forensics firm correlated that evidence with company logs and validated the claim. The researcher confirmed that they deleted all WorkOS data obtained by the agent and did not share it with anyone else.

What information was exposed

WorkOS’s investigation found that the incident affected only data held in its sales and customer support systems. Exposed information included business contact details—names, email addresses, phone numbers, job titles and company affiliations—as well as customer account histories and information about sales and customer-relationship information. Customer communications included summaries and excerpts from sales calls, support discussions and customer Slack conversations; a limited number of support communications included end-user email addresses. Operational metadata included information about customers’ use of WorkOS products, including product usage and connection or directory health.

A legacy tool without platform-level safeguards

The affected tool was an internal application that the company’s go-to-market teams used to look up and manage account information. It aggregated data from the company’s CRM and its customer support and customer communication systems. The tool was hosted on a legacy internal tools platform; it had not yet been migrated to the updated platform, which WorkOS said was equipped with stronger baseline controls.

WorkOS identified four contributing protection gaps. Overly permissive access controls exposed the API endpoints publicly, and the API accepted a predictable, weak credential intended for local development that did not meet the company’s security requirements and was deployed to the tool’s production instance. After discovering the endpoint, the agent was able to authenticate with the credential. The API lacked rate limiting or throttling, and the agent executed rapid requests to extract records in bulk on October 30.

How WorkOS responded

WorkOS removed public access to the affected tool on October 30 and removed its weak credential authentication path between October 30 and 31, while revoking or rotating credentials for every connected service. On October 31, the company blocked internet access to all internally developed tools at its network edge. WorkOS verified centralized logging of network traffic to internal tools on November 2.

As of November 5, WorkOS said it was moving its remaining internal applications from the legacy internal tools platform to the updated platform, adding controls against weak or development-only secrets being deployed to production systems, and adding alerts for unusual access patterns and request volumes on internal tools and the systems they connect to. The company began regularly testing its internet-facing systems with ARTEX on November 3, focusing on systems that were unnecessarily exposed and credentials that can be guessed.
