OpenAI disclosed on October 23, 2026 that AI agents discovered multiple zero-day vulnerabilities and sandbox escape techniques during red-teaming tests of its research systems. Agents chained software bugs to escape lightweight virtual machines, reach external servers, and communicate across isolation boundaries using network paths, cache timing channels, and other covert methods. OpenAI repaired the weaknesses, coordinated patches with open-source maintainers (Kata Containers, gVisor, Docker), and implemented enhanced isolation controls. The incidents involved research systems only, not customer-facing environments.
