漏洞描述
A Server-Side Request Forgery (SSRF) vulnerability exists in parisneo/lollms versions prior to 2.2.0. The /api/files/export-content endpoint processes Markdown image URLs by downloading them via _download_image_to_temp() in backend/routers/files.py without any validation, allowing an unauthenticated attacker to supply arbitrary URLs (e.g. cloud metadata endpoints or internal services) that the server will fetch, enabling internal network access, cloud metadata access, information disclosure, port scanning, and potentially remote code execution.
