From 0b7133c4ce28c1dd46eca96b9fcc0bdc93165469 Mon Sep 17 00:00:00 2001 From: BazookaMusic Date: Thu, 30 Apr 2026 17:39:09 +0200 Subject: [PATCH 01/17] JS: Add prompt injection detection (CWE-1427) for OpenAI, Anthropic, and Google GenAI SDKs Add experimental CodeQL query detecting prompt injection vulnerabilities in JavaScript/TypeScript applications using AI SDK libraries.

Prompts can be constructed to bypass the original purposes of an agent and lead to sensitive data leak or +operations that were not intended.

+ + + +

Sanitize user input and also avoid using user input in developer or system level prompts.

+ + + +

In the following examples, the cases marked GOOD show secure prompt construction; whereas in the case marked BAD they may be susceptible to prompt injection.

    If user-controlled data is included in a system prompt, an attacker can manipulate the instructions +that govern the AI model's behavior, bypassing intended restrictions and potentially causing sensitive +data leaks or unintended operations.

    Do not include user input in system-level or developer-level prompts. If user input must influence +the system prompt, validate it against a fixed allowlist of permitted values.

    In the following example, a user-controlled value is inserted directly into a system-level prompt +without validation, allowing an attacker to manipulate the AI's behavior.

User-controlled data flows into system prompts for LLM calls. + +--- + +### 4. huggingface/responses.js — **TP** + +**Finding:** `responses.ts:271` +**Description:** An open API endpoint populates the system prompt directly from request data. There is no authentication guarding the endpoint, meaning any caller can control the system-level instructions sent to the model. + +--- + +### 5. FlowiseAI/Flowise — **TP** + +**Finding:** `assistants/index.ts:107` +**Description:** User input flows into the OpenAI Assistants API `instructions` field. The `instructions` field is a developer-level system prompt — it defines the assistant's behavior and is not designed for end-user content. Even though Flowise has RBAC, authenticated users can craft `instructions` that affect other users' conversations with the created assistant. Exposing this field to user input is a prompt injection vector regardless of authentication. + +--- + +### 6. sjinnovation/CollabAI (×2 findings) — **TP** + +**Finding:** `openai.js` (2 paths) +**Description:** The POST route for creating OpenAI assistants does **not** have `authenticateUser` middleware applied. Unauthenticated users can create OpenAI assistants with arbitrary `instructions`, directly controlling the system prompt. The missing auth middleware is visible in the route definition — other routes in the same file do use `authenticateUser`. + +--- + +### 7. theodi/chat2db — **TP** + +**Finding:** `openaiClient.js:49` +**Description:** No authentication on the `/v1/chat/completions` route. The route accepts a `messages` array from the client, which can include `role: "system"` messages. An unauthenticated caller can fully override the system prompt. + +--- + +### 8. torarnehave1/mystmkra.io — **TP** + +**Finding:** `assistants.js:58` +**Description:** No authentication on `/assistants/*` routes. An `isAuthenticated` middleware exists in the codebase but is **not applied** to the assistant routes. Unauthenticated users can create or modify assistants with arbitrary instructions, controlling the system prompt. + +--- + +### 9. kvadou/franchise-manager — **TP** + +**Finding:** `generation.ts:449` +**Description:** User-controlled `moduleContext.title` and `moduleContext.description` (from `request.json()`) are concatenated directly into the system prompt. Even with authentication, this is a prompt injection vector: a user can embed instructions like "Ignore all previous instructions" in the title/description fields, overriding the developer's intended system prompt behavior. + +--- + +### 10. armando3069/AI-Inbox — **FP** + +**Finding:** `ai-assistant.service.ts:121` +**Description:** The system prompt tone is selected from a hardcoded `TONE_PROMPTS` map. User input selects which tone to use (e.g., "professional", "casual"), but the actual prompt text is developer-controlled. The false positive arose from CodeQL's array taint propagation — user-tainted content in a `{role:"user"}` message caused the entire messages array to appear tainted, including the `{role:"system"}` message with the hardcoded tone. **The `UserRoleMessageContentBarrier` now correctly blocks this.** + +--- + +### 11. mckaywrigley/chatbot-ui — **FP** + +**Finding:** `anthropic/route.ts:67` +**Description:** Users authenticate via Supabase and provide their own Anthropic API key. The "system prompt" is a personal configuration set by the user for their own chatbot instance. The user is effectively the developer in this context — they are configuring their own model's behavior using their own API key. There is no multi-tenant risk; the system prompt only affects the user who set it. + +--- + +## Verdict Summary + +| # | Repository | Finding Location | Verdict | Key Factor |

    If untrusted input is included in a user-role prompt sent to an AI model, an attacker can inject +instructions that manipulate the model's behavior. This is known as indirect prompt injection +when the malicious content arrives through data the model processes, or direct prompt injection +when the attacker controls the prompt directly.

    + +

    Unlike system prompt injection, user prompt injection targets the user-role messages. Although +user messages are expected to carry user input, passing unsanitized data directly into structured +prompt templates can still allow an attacker to override intended instructions, extract sensitive +context, or trigger unintended tool calls.

    +     + + +

    To mitigate user prompt injection:

    +
      +
    • Validate user input against a fixed allowlist of permitted values before including it in a prompt.
      • +
    • Use parameterized prompt templates that clearly separate instructions from user data.
      • +
    • Apply output filtering to detect and block responses that indicate prompt injection attempts.
      • +
    +     + + +

    In the following example, user-controlled data is inserted directly into a user-role prompt +without any validation, allowing an attacker to inject arbitrary instructions.

    + +

    The fix validates the user input against a fixed allowlist of permitted values before +including it in the prompt.

    Do not include user input in system-level or developer-level prompts or tool descriptions. Use methods meant for user input or messages with a "user" role to provide user content or context to the AI model. + +If user input must influence the system prompt or tool description, validate it against a fixed allowlist of permitted values.

    -

    The fix validates the user input against a fixed allowlist of permitted values before -including it in the prompt.

    +

    One way to fix this is to provide the user-controlled value in a message with the "user" role, +rather than including it in the system prompt. The model then treats it as user content instead of +as a trusted instruction.

    + +

    Alternatively, if the user input must influence the system prompt, validate it against a fixed +allowlist of permitted values before including it in the prompt.

     + +

    Prompt injection is not limited to system prompts. In the following example, which uses an agentic +framework, a user-controlled value is included in the description of a tool that is exposed to the +model. An attacker can use this to manipulate the model's behavior in the same way.

    + +

    The fix keeps the tool description as a fixed, trusted string and passes the user-controlled topic +as part of the user input instead, so the model treats it as user content rather than as a trusted +instruction.
