+## Threat Model for qs (querystring parsing library)
+
+### 1. Library Overview
+
+- **Library Name:** qs
+- **Brief Description:** A JavaScript library for parsing and stringifying URL query strings, supporting nested objects and arrays. It is widely used in Node.js and web applications for processing query parameters[2][6][8].
+- **Key Public APIs/Functions:** `qs.parse()`, `qs.stringify()`
+
+### 2. Define Scope
+
+This threat model focuses on the core parsing and stringifying functionality, specifically the handling of nested objects and arrays, option validation, and cycle management in stringification.
+
+### 3. Conceptual System Diagram
+
+```
+Caller Application → qs.parse(input, options) → Parsing Engine → Output Object
+                           │
+                           └→ Options Handling
+
+Caller Application → qs.stringify(obj, options) → Stringifying Engine → Output String
+                           │
+                           └→ Options Handling
+                           └→ Cycle Tracking
+```
+
+**Trust Boundaries:**
+- **Input string (parse):** May come from untrusted sources (e.g., user input, network requests)
+- **Input object (stringify):** May contain cycles, which can lead to infinite loops during stringification
+- **Options:** Provided by the caller
+- **Cycle Tracking:** Used only during stringification to detect and handle circular references
+
+### 4. Identify Assets
+
+- **Integrity of parsed output:** Prevent malicious manipulation of the output object structure, especially ensuring builtins/globals are not modified as a result of parse[3][4][8].
+- **Confidentiality of processed data:** Avoid leaking sensitive information through errors or output.
+- **Availability/performance for host application:** Prevent crashes or resource exhaustion in the consuming application.
+- **Security of host application:** Prevent the library from being a vector for attacks (e.g., prototype pollution, DoS).
+- **Reputation of library:** Maintain trust by avoiding supply chain attacks and vulnerabilities[1].
+
+### 5. Identify Threats
+
+| Component / API / Interaction         | S  | T  | R  | I  | D  | E  |
+|---------------------------------------|----|----|----|----|----|----|
+| Public API Call (`parse`)             | –  | ✓  | –  | ✓  | ✓  | ✓  |
+| Public API Call (`stringify`)         | –  | ✓  | –  | ✓  | ✓  | –  |
+| Options Handling                      | ✓  | ✓  | –  | ✓  | –  | ✓  |
+| Dependency Interaction                | –  | –  | –  | –  | ✓  | –  |
+
+**Key Threats:**
+- **Tampering:** Malicious input can, if not prevented, alter parsed output (e.g., prototype pollution via `__proto__`, modification of builtins/globals)[3][4][8].
+- **Information Disclosure:** Error messages may expose internal details or sensitive data.
+- **Denial of Service:** Large or malformed input can exhaust memory or CPU.
+- **Elevation of Privilege:** Prototype pollution can lead to unintended privilege escalation in the host application[3][4][8].
+
+### 6. Mitigation/Countermeasures
+
+| Threat Identified                                 | Proposed Mitigation |
+|---------------------------------------------------|---------------------|
+| Tampering (malicious input, prototype pollution)  | Strict input validation; keep `allowPrototypes: false` by default; use `plainObjects` for output; ensure builtins/globals are never modified by parse[4][8]. |
+| Information Disclosure (error messages)           | Generic error messages without stack traces or internal paths. |
+| Denial of Service (memory/CPU exhaustion)         | Enforce `arrayLimit` and `parameterLimit` with safe defaults; enable `throwOnLimitExceeded`; limit nesting depth[7]. |
+| Elevation of Privilege (prototype pollution)      | Keep `allowPrototypes: false`; validate options against allowlist; use `plainObjects` to avoid prototype pollution[4][8]. |
+
+### 7. Risk Ranking
+
+- **High:** Denial of Service via array parsing or malformed input (historical vulnerability)
+- **Medium:** Prototype pollution via options or input (if `allowPrototypes` enabled)
+- **Low:** Information disclosure in errors
+
+### 8. Next Steps & Review
+
+1. **Audit option validation logic.**
+2. **Add depth limiting to nested parsing and stringification.**
+3. **Implement fuzz testing for parser and stringifier edge cases.**
+4. **Regularly review dependencies for vulnerabilities.**
+5. **Keep documentation and threat model up to date.**
+6. **Ensure builtins/globals are never modified as a result of parse.**
+7. **Support round-trip consistency between parse and stringify as a non-security goal, with the right options[5][9].**
