CVE-2024-2952

Estado: AnalizadaCrítica (9.8)—

BerriAI/litellm es vulnerable a Server-Side Template Injection (SSTI) a través del endpoint `/completions`. La vulnerabilidad surge del método `hf_chat_template` que procesa el parámetro `chat_template` del archivo `tokenizer_config.json` a través del motor de plantillas Jinja sin una sanitización adecuada. Los atacantes pueden aprovechar esto creando archivos maliciosos `tokenizer_config.json` que ejecutan código arbitrario en el servidor.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
