Safety vulnerability ID: 71611
The information on this page was manually curated by our Cybersecurity Intelligence Team.
Affected versions of the `langchain` package are vulnerable to Server-Side Request Forgery (SSRF) due to inadequate handling of external URLs in `recursive_url_loader.py`. The vulnerability exists because the preventive measure of setting the `prevent_outside` parameter to True is bypassed, allowing the crawler to interact with unauthorized servers. An attacker controlling an external server can exploit this by embedding links that appear to be internal, such as `https://example.completely.different/my_file.html`, leading the crawler to fetch and process potentially malicious files.
