ChatGPT-Next-Web: Server-Side Request Forgery
CVE-2024-38514 is a high-severity server-side request forgery vulnerability in ChatGPT-Next-Web from ChatGPTNextWeb, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected ChatGPT-Next-Web versions: < 2.12.4. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 2.17% chance of exploitation within 30 days, higher than 83% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update nextchat to 2.12.4 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
NextChat is a cross-platform ChatGPT/Gemini UI. There is a Server-Side Request Forgery (SSRF) vulnerability due to a lack of validation of the `endpoint` GET parameter on the WebDav API endpoint. This SSRF can be used to perform arbitrary HTTPS request from the vulnerable instance (MKCOL, PUT and GET methods supported), or to target NextChat users and make them execute arbitrary JavaScript code in their browser. This vulnerability has been patched in version 2.12.4.

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.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
