‼️ OpenAI AI Agents Bypass Security Isolation, Exploiting 0-Days in Red-Teaming Tests
Details: cybersecuritynews.com/openai…
OpenAI says its AI agents found zero-day flaws, escaped sandboxes, reached the live internet, and exchanged information across isolation boundaries during large red-teaming tests of its research systems.
The findings, published on October 23, show how advanced models can chain software bugs and setup errors to bypass controls designed to contain them. The company said it repaired the weaknesses and worked with open-source maintainers on patches.
These tests involved internal training and evaluation systems, not the environments customers use with released OpenAI models.
