CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-38514 is a high-severity SSRF (CWE-918) vulnerability. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 19% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
NextChat, a cross-platform ChatGPT/Gemini user interface, contains a server-side request forgery vulnerability in its WebDAV API endpoint. The flaw stems from missing validation of the endpoint GET parameter, allowing an attacker to supply arbitrary URLs. This affects all versions prior to the patch released in 2.12.4 and is tracked as CWE-918 with a CVSS 3.1 score of 7.4.
An unauthenticated remote attacker can exploit the issue over the network to force the NextChat instance to issue HTTPS requests using the MKCOL, PUT, and GET methods against internal or external targets. The same vector can also be used to deliver malicious payloads that execute arbitrary JavaScript in the browsers of other NextChat users who interact with the affected endpoint.
The official GitHub Security Advisory GHSA-gph5-rx77-3pjg and the associated commit dad122199a85c2f12277593973e1784b212adf5e confirm that the vulnerability is resolved in version 2.12.4; administrators are advised to upgrade immediately and to restrict or monitor access to the WebDAV API until the update is applied.
The EPSS score has reached a peak of 0.7256 with a current value of 0.7111, indicating sustained exploitation interest after disclosure.

Vulnerability Data
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…

Mitigating Controls (NIST 800-53 r5) AI
Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.
Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.
Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure development practices directly include input validation and destination allow-listing that prevent SSRF.
Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.
Vulnerability identification processes can discover and record SSRF flaws in web applications.
Network segmentation and egress controls can limit the damage from successful SSRF requests.
