lobe-chat: Server-Side Request Forgery

CVE-2024-32965 is a high-severity server-side request forgery vulnerability in lobe-chat from Lobehub, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.19.13 as the first without the flaw, so updating lobe-chat to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 26.1% chance of exploitation within 30 days, which is in the top 1.98% of all scored CVEs.

EPSS places it among the vulnerabilities most likely to be exploited soon.

What to do

  1. Update lobe-chat to 1.19.13 or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Lobe Chat is an open-source, AI chat framework. Versions of lobe-chat prior to 1.19.13 have an unauthorized ssrf vulnerability. An attacker can construct malicious requests to cause SSRF without logging in, attack intranet services, and leak sensitive information. The jwt token header X-Lobe-Chat-Auth strored proxy address and OpenAI API Key, can be modified to scan an internal network in the target lobe-web environment. This issue has been addressed in release version 1.19.13 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

The underlying weakness: Server-Side Request Forgery

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

How developers prevent this class of flaw

  • If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
  • If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
