Multi-agent AI handoffs can leak sensitive data without human review

First reported

The Algorithm ran this on .

  • AI agents that pass outputs to other agents can move restricted data along without anyone checking it.
  • A hypothetical sales case shows an agent pulling confidential pricing and handing it to a second agent that drafts a proposal.
  • Neither handoff in the example includes a human review step, which is the core security gap.
