Summary

CVE-2024-6587 is a high-severity SSRF (CWE-918) vulnerability in Litellm Litellm. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as APIs and Models; in the Privacy and Disclosure risk domain.

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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A Server-Side Request Forgery (SSRF) vulnerability, tracked as CVE-2024-6587, affects berriai/litellm version 1.38.10. The flaw resides in the handling of the api_base parameter supplied to the POST /chat/completions endpoint, which causes the application to issue an outbound request to an arbitrary domain while embedding the configured OpenAI API key in the request.

An unauthenticated remote attacker can supply a malicious api_base value pointing to an attacker-controlled server. When the application processes the request, it forwards the API key to that server, enabling the attacker to capture the credential and obtain unauthorized access to the associated OpenAI account and resources.

The referenced GitHub commit ba1912afd1b19e38d3704bb156adf887f91ae1e0 contains the fix applied to the litellm codebase. The associated huntr.com report provides additional technical detail on the issue and its resolution.

The vulnerability carries a CVSS score of 7.5 and an EPSS score of 0.8863. Because litellm is widely used to proxy requests to large-language-model APIs, the flaw directly impacts AI/ML infrastructure that relies on external API keys.

Vulnerability Data

A Server-Side Request Forgery (SSRF) vulnerability exists in berriai/litellm version 1.38.10. This vulnerability allows users to specify the `api_base` parameter when making requests to `POST /chat/completions`, causing the application to send the request to the domain specified by `api_base`. This…

more

request includes the OpenAI API key. A malicious user can set the `api_base` to their own domain and intercept the OpenAI API key, leading to unauthorized access and potential misuse of the API key.

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.
