Starlette - Improper Validation of Unsafe Equivalence in Input

A flaw was found in Starlette, a lightweight ASGI Asynchronous Server Gateway Interface framework. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP Host request header. This malformed header could cause the request.url to be incorrectly reconstructed, leading...

LiteLLM - Command Injection

A critical unauthenticated remote code execution vulnerability exists in LiteLLM due to improper input handling in the MCP stdio test endpoint. An attacker can send a specially crafted request to the /mcp-rest/test/connection endpoint with controlled parameters, resulting in arbitrary command...

CVE-2026-48746

vLLM OpenAI auth bypass (CVE-2026-48746) affects vLLM versions 0.3.0 through 0.21.0. Root cause: ASGI servers and Starlette trust the Host header from the request scope, enabling manipulation of the reconstructed URL path and bypassing the OpenAI API AuthenticationMiddleware for routes beginning ...

CVE-2026-48746 vLLM: OpenAI auth bypass

vLLM is an inference and serving engine for large language models LLMs. From 0.3.0 until 0.22.0, a vulnerability in ASGI web servers and starlette's trust on those web servers enables an authentication bypass of the OpenAI API AuthenticationMiddleware. It allows to use the API without providing t...

CVE-2026-54282

Starlette is a lightweight ASGI framework/toolkit. Prior to 1.3.0, the HTTP request path is not validated before being used to reconstruct request.url. Because request.url is rebuilt by concatenating scheme://hostpath and re-parsing the result, a path that does not begin with / for example...

CVE-2026-54283

CVE-2026-54283

Starlette (Python-starlette) from 0.4.1 through 1.3.1 is affected by CVE-2026-54283, where request.form() fails to apply max_fields/max_part_size for application/x-www-form-urlencoded, allowing an unauthenticated attacker to send a URL-encoded body with unbounded fields or field size. This result...
