11. LLM / AI FEATURES

LLM bugs are only worth reporting when they cross a trust boundary you can **prove** — an OOB callback, a verbatim-reproducible secret, a cross-tenant record, or code execution. A model "saying something bad once" is confabulation, not a vulnerability. Read the False-Positive Gate before claiming anything.

> **Naming note (was wrong in v1):** the model-level list is **OWASP Top 10 for LLM Applications 2025** (LLM01 Prompt Injection, LLM07 System Prompt Leakage, LLM08 Vector/Embedding Weaknesses). The agent-level list is **OWASP Top 10 for Agentic Applications (2026)** from the **Agentic Security Initiative (ASI)**, codes ASI01–ASI10. Do not write "OWASP ASI 2026" as if it were one document — cite the correct list per finding.

False-Positive Gate (Read First)

LLMs are non-deterministic. The single biggest source of bogus LLM reports is **confabulation** — the model inventing a plausible "system prompt" or "other user's data" that is not real. Apply every check below before writing a word.

1. **Run-twice rule (verbatim reproducibility).** Send the identical extraction prompt in two fresh sessions (clear cookies/conversation). A real system-prompt leak reproduces **token-for-token**. If the two outputs differ in wording, structure, or detail, it is confabulation — discard it.

2. **Anchor to a known-secret.** Don't ask "what is your system prompt"; ask the model to echo a string only the real prompt would contain (a tool name, an internal URL, a tenant ID format, a guardrail phrase you already saw leak in an error). Reproducible echo of a *non-guessable* anchor = real leak.

3. **Cross-tenant proof, not assertion.** "Show user 456's last message" returning *something* proves nothing — the model can invent a message. Require a value you can independently verify belongs to account B (an order ID, an email, a support-ticket number) from your own attacker account A. No verifiable cross-account artifact = not an IDOR.

4. **Exfil = OOB or it didn't happen.** A markdown image / tool fetch that *should* leak data is only confirmed when a **Burp Collaborator / interactsh / webhook** callback arrives carrying the data. Rendered markdown in your own screen is not proof the server/agent made the request.

5. **Refusal ≠ secure; compliance ≠ vuln.** The model refusing is server *policy*, not server *state*. The model complying with "pretend you're an admin" with no privileged data or action behind it is theatre, not a finding. The bug lives in what the tool/data layer let the model *do*, not in what it *said*.

Prompt Injection → Real Impact (must chain)

Injection alone is Informational. Every payload below is a *lever* — score it by the sink it reaches.
