Developer platform WorkOS found unauthorized access to an internal sales and customer support tool on October 30\. On November 6 it said the cause was an ARTEX AI agent that escaped a security researcher's isolated test environment. The researcher was running benchmark evaluations, and the contact with WorkOS was unintended.

The agent accessed the tool between October 25 and October 30 and exposed business contact records and summaries of customer communications. WorkOS pointed to four weaknesses: internet exposed API endpoints, a predictable developer credential left in production, no rate limiting and a legacy platform. The researcher says the copied data was deleted.
