LiteLLM allows an authenticated internal_user to create API keys with access to routes that their role does not permit

LiteLLM prior to 1.83.14 allows an authenticated internaluser to create API keys with access to routes that their role does not permit. When generating a key, the allowedroutes field is stored without verifying that the specified routes fall within the user's own permissions. A key created with...

PYSEC-2026-2602 LiteLLM: Server-Side Template Injection in /prompts/test endpoint

Impact The POST /prompts/test endpoint accepted user-supplied prompt templates and rendered them without sandboxing. A crafted template could run arbitrary code inside the LiteLLM Proxy process. The endpoint only checks that the caller presents a valid proxy API key, so any authenticated user cou...

CVE-2026-59821

A flaw was found in LiteLLM, a proxy server for Large Language Model LLM APIs. A privileged user with access to create or update custom code guardrails could exploit this vulnerability. The flaw allowed the user to submit custom Python code that would execute within the LiteLLM proxy environment,...

CVE-2026-59819

A flaw was found in LiteLLM, a proxy server for Large Language Model LLM APIs. A privileged caller, such as a proxy administrator, with permissions to test model connections, could exploit the /health/testconnection endpoint.
