Severity ?

3.7 (Low) - CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:N

Summary

langchain Server-Side Request Forgery vulnerability

Details

With the following crawler configuration:

```python from bs4 import BeautifulSoup as Soup

url = "https://example.com" loader = RecursiveUrlLoader( url=url, max_depth=2, extractor=lambda x: Soup(x, "html.parser").text ) docs = loader.load() ```

An attacker in control of the contents of https://example.com could place a malicious HTML file in there with links like "https://example.completely.different/my_file.html" and the crawler would proceed to download that file as well even though prevent_outside=True.
