An agent can be turned without any injection at all
Defences concentrate on detecting malicious input. A prompt that is merely scoped too loosely can be exploited directly - no injection needed, and nothing for an injection filter to catch.
This is the most useful finding in the vendor threat research and it cuts against where most effort goes. If the instructions do not explicitly refuse out-of-scope requests, an ordinary well-formed question can extract the instruction text or the list of tools it can call, which is the map an attacker needs for everything that follows. Injection remains the more potent vector once present - capable of leaking data, misusing tools and subverting behaviour - but a filter for it is not a substitute for bounding what the agent will agree to do when asked politely.
How to fix it — 1 approach, 3 steps
Make the agent refuse out-of-scope requests by construction
Write explicit refusal of out-of-scope work, and of requests for its own instructions or tool list, into every deployed agent - then test it.
Done when A dated test record shows each live agent refusing an out-of-scope request and refusing to disclose its instructions and tool list, re-run after the most recent instruction change.
- Ask each live agent for its instructions and its tool list, and record what it gives up.
- Add explicit refusal of out-of-scope requests, and of naming its own tools, to the instructions.
- Re-test after every instruction change, not only at first deployment.

| AWSHyperscaler · April 2025 | Navigating the security landscape of generative AIOur reading Names a route that carries no malicious instruction at all: the window holds a fixed amount, and an adversary who floods it with bulk content can push the earlier instructions out of what the model still sees. Nothing arrives for a filter to match, and what follows is behaviour nobody predicted, data leaving, or an action taken without authority.Filling the context until the instructions fall out | names it |
| IBMHyperscaler | Securing enterprise AI at scaleOur reading Names the shape directly: agents authenticate once and carry inherited permissions across boundaries they were never scoped for, and the answer offered by its own technology chief is an agent built for one task with a narrow scope enforced on it.Where the permissions run wider than the task | names it |
| Palo Alto NetworksVendor · May 2025 | Agentic AI threatsOur reading Reports that poorly scoped or unsecured prompts can be exploited without any explicit injection, and that instruction text and the list of callable tools can be extracted this way. Written by a security vendor, whose interest points the same way as the finding.Injection is not always necessary | names it |
| AWSHyperscaler · April 2025 | Navigating the security landscape of generative AIOur reading Qualifies the defence where injection genuinely is the route: the web application firewall already in place is judged not to go far enough, and what is asked for alongside it is inspection that reads the surrounding context, checks repeated at several stages, and in some cases a model trained specifically on the inputs being screened.The filter most organizations already own does not reach | qualifies it |
| Palo Alto NetworksVendor · May 2025 | Agentic AI threatsOur reading Proposes building refusal of out-of-scope requests, and of revealing its own instructions or tools, into the agent instructions themselves, ahead of any runtime filter.Refuse out-of-scope requests explicitly | proposes a fix |
