Vulnerability	Vulnerable Version
H Authorization Bypass Through User-Controlled Key litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the `add_new_model` and `can_user_make_team_model_call` functions in `model_management_endpoints.py`, which authorize the caller by role alone and never inspect the values supplied in `litellm_params`. A user with team administrator access can read any environment variable of the proxy process, including the proxy master key, by registering a model whose `api_key` is an `os.environ/<NAME>` reference and whose `api_base` points to a host they control, then invoking it so that `get_secret` resolves the variable and `_resolve_db_litellm_param` sends it to that host as the outbound `Authorization` header. This requires `STORE_MODEL_IN_DB` to be enabled and an enterprise license, which is what makes the team administrator role available. Note: A fix is unlikely. In https://github.com/BerriAI/litellm/commit/5862be3e79154ce5ac8a736c77c7c3614fac40fb, project maintainers removed the field whitelist and the team-scope short-circuit in `_resolve_db_litellm_param` deliberately, describing universal `os.environ/` resolution for team-scoped rows as an intended threat-model expansion that trusts team administrators to read environment variables, and placing the trust boundary on who the deployment grants team administrator rather than on what those administrators may reference.

H Weak Authentication litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Weak Authentication via the JWT authentication flow's email-based fallback lookup, which does not verify the `email_verified` claim before resolving a user identity. An attacker holding a valid JWT from the configured identity provider can present a token containing an unverified email address that matches a victim's account, causing the system to authenticate the attacker as that victim and inherit their role, including `proxy_admin` privileges. This also permanently overwrites the victim's stored identity binding, granting the attacker persistent unauthorized access to administrative endpoints that expose API keys and user management functions.

M Insufficient Session Expiration litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Insufficient Session Expiration in the `get_redirect_response_from_openid()` function of the SSO Authentication Flow process. An attacker can cause premature session termination by manipulating authentication responses remotely, potentially leading to unauthorized session expiration and disruption of user access.

M Missing Authentication for Critical Function litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Missing Authentication for Critical Function in the `/sso/debug/login` and `/sso/debug/callback` endpoints in the SSO Debug Flow. An attacker can gain unauthorized access and potentially manipulate sensitive information by sending crafted requests to the affected endpoint.

L Incorrect Authorization litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Incorrect Authorization in the `user_api_key_auth.py` file of the M2M JWT Handler. An attacker can gain unauthorized access to resources by exploiting insufficient authorization checks. Note: This is only exploitable if the attacker possesses valid but limited credentials and can craft specific JWTs to bypass intended access controls. How to fix Incorrect Authorization? There is no fixed version for `litellm`.	[0,)
H Insufficient Session Expiration litellm is a Library to easily interface with LLM API providers Affected versions of this package are vulnerable to Insufficient Session Expiration in the `authenticate_user` function. An attacker can gain unauthorized access or maintain access to sensitive information by exploiting session management flaws. How to fix Insufficient Session Expiration?
