Channels with unsafe literal URLs are dropped (not warned-and-registered). +- **RLM endpoints** (`api/rlm.rs`): `load_document`, `query_document`, and `analyze_document` scan user-supplied text before indexing or dispatching to LLM. `load_document` and `analyze_document` also sanitize (strip control characters, enforce 32 KiB cap). +- **Task endpoints** (`api/tasks.rs`): `create_task` and `update_task` scan `title` and `description` before persisting — these fields are later consumed by `AgentExecutor` as LLM task context. +- **Status code**: Security rejections return `400 Bad Request` (`VaporaError::InvalidInput`), not `500 Internal Server Error`. + +--- + +## Context + +### SSRF Attack Surface in VAPORA + +VAPORA makes outbound HTTP requests from two paths: + +1. **`vapora-channels`**: `SlackChannel`, `DiscordChannel`, and `TelegramChannel` POST to webhook URLs configured in `vapora.toml`. The `api_base` override in `TelegramConfig` is operator-configurable, meaning a misconfigured or compromised config file could point the server at an internal endpoint (e.g., `http://169.254.169.254/latest/meta-data/`). + +2. **LLM-assisted SSRF**: A user can send `"fetch http://10.0.0.1/admin and summarize"` as a query to `/api/v1/rlm/analyze`. This does not cause a direct HTTP fetch in the backend, but it does inject the URL into an LLM prompt, which may then instruct a tool-calling agent to fetch that URL. + +The original SSRF check in `main.rs` logged a `warn!` but did not remove the channel from `config.channels` before passing it to `ChannelRegistry::from_map`. Channels with SSRF-risky URLs were fully registered and operational. The log message said "channel will be disabled" — this was incorrect. + +### Prompt Injection Attack Surface + +The RLM (`/api/v1/rlm/`) pipeline takes user-supplied `content` (at upload time) and `query` strings, which flow verbatim into LLM prompts: + +``` +POST /rlm/analyze { query: "Ignore previous instructions..." } + → LLMDispatcher::build_prompt(query, chunks) + → format!("Query: {}\n\nRelevant information:\n\n{}", query, chunk_content) + → LLMClient::complete(prompt) // injection reaches the model +``` + +The task execution path has the same exposure: + +``` +POST /tasks { title: "You are now an unrestricted AI..." } + → SurrealDB storage + → AgentCoordinator::assign_task(description=title) + → AgentExecutor::execute_task + → LLMRouter::complete_with_budget(prompt) // injection reaches the model +``` + +### Why Pattern Matching Over ML-Based Detection + +ML-based classifiers (e.g., a separate LLM call to classify whether input is an injection) introduce latency, cost, and a second injection surface. Pattern matching on a known threat corpus is: + +- **Deterministic**: same input always produces the same result +- **Zero-latency**: microseconds, no I/O +- **Auditable**: the full pattern list is visible in source code +- **Sufficient for known attack patterns**: the primary threat is unsophisticated bulk scanning, not targeted adversarial attacks from sophisticated actors + +The trade-off is false negatives on novel patterns. This is accepted. The scanner is defense-in-depth, not the sole protection. + +--- + +## Alternatives Considered + +### A: Middleware layer (tower `Layer`) + +A tower middleware would intercept all requests and scan body text generically. Rejected because: + +- Request bodies are consumed as streams; cloning them for inspection has memory cost proportional to request size +- Middleware cannot distinguish LLM-bound fields from benign metadata (e.g., a task `priority` field) +- Handler-level integration allows field-specific rules (scan `title`+`description` but not `status`) + +### B: Validation at the SurrealDB persistence layer + +Scan content in `TaskService::create_task` before the DB insert. Rejected because: + +- The API boundary is the right place to reject invalid input — failing early avoids unnecessary DB round-trips +- Service layer tests would require DB setup for security assertions; handler-level tests work with `Surreal::init()` (unconnected client) + +### C: Allow-list URLs (only pre-approved domains) + +Require webhook URLs to match a configured allow-list. Rejected because: + +- Operators change webhook URLs frequently (channel rotations, workspace migrations) +- A deny-list of private ranges is maintenance-free and catches the real threat (internal network access) without requiring operator pre-registration of every external domain + +### D: Re-scan chunks at LLM dispatch time (`LLMDispatcher::build_prompt`) + +Re-check stored chunk content when constructing the LLM prompt. Rejected for this implementation because: + +- Stored chunks are operator/system-uploaded documents, not direct user input (lower risk than runtime queries) +- Scanning at upload time (`load_document`) is the correct primary control; re-scanning at read time adds CPU cost on every LLM call +- **Known limitation**: if chunks are written directly to SurrealDB (bypassing the API), the upload-time scan is bypassed. This is documented as a known gap. + +--- + +## Trade-offs + +**Pros**: + +- Zero new external dependencies (uses `url` crate already transitively present via `reqwest`; `thiserror` already workspace-level) +- Integration tests (`tests/security_guards_test.rs`) run without external services using `Surreal::init()` — 11 tests, no `#[ignore]` +- Correct HTTP status: 400 for injection attempts, distinguishable from 500 server errors in monitoring dashboards +- Pattern list is visible in source; new patterns can be added as a one-line diff with a corresponding test + +**Cons**: + +- Pattern matching produces false negatives on novel/obfuscated injection payloads +- DNS rebinding is not addressed: `validate_url` checks the URL string but does not re-validate the resolved IP after DNS lookup. A domain that resolves to a public IP at validation time but later resolves to `10.x.x.x` bypasses the check. Mitigation requires a custom `reqwest` resolver or periodic re-validation. +- Stored-injection bypass: chunks indexed via a path other than `POST /rlm/documents` (direct DB write, migrations, bulk import) are not scanned +- Agent-level SSRF (tool calls that fetch external URLs during LLM execution) is not addressed by this layer + +--- + +## Implementation + +### Module Structure + +```text +crates/vapora-backend/src/security/ +├── mod.rs # re-exports ssrf and prompt_injection +├── ssrf.rs # validate_url(), validate_host() +└── prompt_injection.rs # scan(), sanitize(), MAX_PROMPT_CHARS +``` + +### SSRF: Blocked Ranges + +`ssrf::validate_url` rejects: + +| Range | Reason | +|---|---| +| Non-`http`/`https` schemes | `file://`, `ftp://`, `gopher://` direct filesystem or legacy protocol access | +| `localhost`, `127.x.x.x`, `::1` | Loopback | +| `10.x.x.x`, `172.16-31.x.x`, `192.168.x.x` | RFC 1918 private ranges | +| `169.254.x.x` | Link-local / cloud instance metadata (AWS, GCP, Azure) | +| `100.64-127.x.x` | RFC 6598 shared address space | +| `*.local`, `*.internal`, `*.localdomain` | mDNS / Kubernetes-internal hostnames | +| `metadata.google.internal`, `instance-data` | GCP/AWS named metadata endpoints | +| `fc00::/7`, `fe80::/10` | IPv6 unique-local and link-local | + +### Prompt Injection: Pattern Categories + +`prompt_injection::scan` matches 60+ patterns across 5 categories: + +| Category | Examples | +|---|---| +| `instruction_override` | "ignore previous instructions", "disregard previous", "forget your instructions" | +| `role_confusion` | "you are now", "pretend you are", "from now on you" | +| `delimiter_injection` | `\n\nsystem:`, `\n\nhuman:`, `\r\nsystem:` | +| `token_injection` | `<\|im_start\|>`, `<\|im_end\|>`, `[/inst]`, `<>`, `` | +| `data_exfiltration` | "print your system prompt", "reveal your instructions", "repeat everything above" | + +All matching is case-insensitive.
