via sub-technique T1505.003 Web Shell
Inferred from CWE-287.
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Inferred from CWE-287.
Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.
Inferred from CWE-287.
Adversaries may passively sniff network traffic to capture information about an environment, including authentication material passed over the network.
Inferred from CWE-287.

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.84.0, LiteLLM's MCP Streamable HTTP endpoint allowed an unauthenticated attacker to use a fabricated Authorization header to trigger an OAuth2 passthrough fallback path that replaced failed LiteLLM key validation with an empty UserAPIKeyAuth() object, allowing requests to reach MCP tooling without a valid LiteLLM key. This issue is fixed in version 1.84.0.
CVSS measures how bad exploitation would be; EPSS estimates how likely exploitation is within 30 days; the CISA listing means it is already happening. Read them together: a CVSS 9.8 with EPSS 0.04% is usually less urgent than a CVSS 7.2 on the exploited list. Data: NVD, FIRST EPSS, CISA KEV; detail is cached for a week, scores for a day. ATT&CK techniques come from the CTID KEV mappings project where a curated mapping exists, otherwise they are inferred from the weakness class and labelled as such.
