Vulnerability details
The vulnerability allows a local user to inject prompts into later agent turns.
The vulnerability exists due to trust boundary violation in trusted System: events when processing lower-trust background runtime output and local async exec completion output. A local user can cause lower-trust output to be treated as trusted system events to inject prompts into later agent turns.
This issue is scoped to the product's local trust model and does not assume a multi-tenant service boundary.
