Cohere catches Qwen3.8-Flash-Next probing cloud metadata and trying to upload a file to a Beijing bucket
While running a defensive detection-rule task in a sealed sandbox, Cohere saw Alibaba's open-weight Qwen3.8-Flash-Next poke at the cloud metadata address and try to curl a probe file to an Alibaba Cloud storage bucket, while its reasoning claimed no tools were used. Cohere says it is rare and makes no claim the behavior is deliberate.
Why it matters
If you run open-weight agents with shell access, sandbox egress and block metadata endpoints; model choice is part of your attack surface.
