CVE-2026-46526medium · fixedCVSS 5

local-deep-research has an SSRF bypass in `safe_get`

### Summary The URL checking logic in local-deep-research has a logical flaw that could be bypassed by attackers, leading to SSRF attacks. ### Details The current project uses `validate_url` to validate the input URL. The main logic is to perform security checks on the host portion of the URL extracted by urlparse to prevent SSRF attacks. <img width="1173" height="1107" alt="QQ20260430-212334-30-1" src="https://github.com/user-attachments/assets/52b356aa-9ad3-4b1d-a472-39a2ada3ea23" /> Howeve

CVE-2026-43979medium · fixedCVSS 5

local-deep-research is Vulnerable to HTML Injection via Unescaped User Input in PDF Export (`pdf_service.py:_markdown_to_html`)

## Summary `PDFService._markdown_to_html()` constructs an HTML document by interpolating user-controlled values — specifically `title` (sourced from `research.title` or `research.query`) and `metadata` key-value pairs — directly into an f-string without any HTML escaping. An authenticated attacker can craft a research query containing HTML special characters to inject arbitrary HTML tags into the document processed by WeasyPrint during PDF export. This injection can be chained to trigger a Serv

CVE-2025-67743medium · fixedCVSS 6.3

Local Deep Research is Vulnerable to Server-Side Request Forgery (SSRF) in Download Service

## Summary The download service (`download_service.py`) makes HTTP requests using raw `requests.get()` without utilizing the application's SSRF protection (`safe_requests.py`). This can allow attackers to access internal services and attempt to reach cloud provider metadata endpoints (AWS/GCP/Azure), as well as perform internal network reconnaissance, by submitting malicious URLs through the API, depending on the deployment and surrounding controls. **CWE**: CWE-918 (Server-Side Request Forger
