Vulnerability Data

BerriAI/litellm is vulnerable to Server-Side Template Injection (SSTI) via the `/completions` endpoint. The vulnerability arises from the `hf_chat_template` method processing the `chat_template` parameter from the `tokenizer_config.json` file through the Jinja template engine without proper sanitization. Attackers can exploit this by…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

SA-11 requires developer testing and evaluation that can discover failures to neutralize equivalent special elements.

SI-10 Information Input Validation good match

SI-10 requires validation of information inputs, directly stopping incomplete neutralization of equivalent special elements.

SA-8 Security and Privacy Engineering Principles partial match

SA-8 mandates security engineering principles such as complete input validation and sanitization that cover equivalent special-element forms.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect incomplete neutralization but does not prevent the weakness itself.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and neutralization of all equivalent special elements.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for handling special characters and equivalent encodings.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles require consistent canonicalization and neutralization of equivalent inputs.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address proper neutralization of all equivalent special elements.
