LangChain < 0.1.0 SSRF

low Nessus Plugin ID 213562

Synopsis

The remote host is affected by a vulnerability.

Description

The version of LangChain installed on the remote host is prior to 0.1.0. It is, therefore, affected by a SSRF vulnerability. 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`.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to LangChain version 0.1.0 or later.
