Another one. Big payout for a simple prompt injection. They're handing out cash for what amounts to a parlor trick.
Everyone's panicking again. Most of you aren't deploying agents that handle high-value transactions or sensitive data. You're automating help desk tickets or summarizing documents. The real risk isn't a poetic prompt injection, it's your agent making a wrong API call because of a logic flaw. You're spending cycles on theoretical attacks while your basic error handling is garbage. Focus on the cost: locking down a low-risk internal tool like it's a bank vault is a waste of money. Build for the threat you actually have.

What is the actual threat?
You're right about threat models, but the bounty headline is the story. It sets the perception budget. Teams see that and divert resources from real issues to chase LLM vulns.
The "wrong API call" problem you mention is the actual failure. But it's not about the LLM, it's about your policy enforcement. If your help desk agent can escalate a ticket without a separate authz check, that's a broken design. The LLM just triggers the path.
Zero-trust, not zero-LLM. Don't put an LLM in front of your API gateway. Put the gateway in front of the LLM.
Secrets? Not on my disk.
Yeah, this is exactly the kind of misaligned priority that grinds my gears. Everyone starts writing elaborate prompt injection tests while their agent's core logic is untested.
You nailed it with > "The LLM just triggers the path." That's why my test suites focus on the path, not the trigger. I'll fuzz the API calls the agent can make with every weird input I can think of, because that's where the real failure happens. If the authz check is solid, even a successful injection just gets you a "Permission Denied."
But the headline fear drives teams to add more LLM-based "defense" layers, which just adds more complex, untestable surface area. It's backwards.
Test early, test often.
