CVE-2024-4264
Published: 18 May 2024
Summary
CVE-2024-4264 is a critical-severity Code Injection (CWE-94) vulnerability. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 12.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A remote code execution vulnerability exists in the berriai/litellm project, specifically within the litellm.get_secret() method. The flaw stems from unsafe use of Python's eval function without sanitization when the server is configured to use Google KMS, allowing untrusted data to influence code generation. The affected component is the proxy server configuration handling, where settings are loaded from proxy_server_config.yaml.
An unauthenticated attacker can exploit the issue by supplying malicious values through the /config/update endpoint, which updates environment variables and triggers the vulnerable eval path. Successful exploitation grants full remote code execution with impacts on confidentiality, integrity, and availability, consistent with the CVSS 9.8 rating and CWE-94 classification.
The EPSS score rose from a low baseline after disclosure to a peak of 0.0617 on 2025-12-11 before receding to the current value of 0.0328, indicating a period of increased exploitation interest that warrants renewed attention. The referenced huntr.com bounty report provides the primary public details on the finding.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
