CVE-2026-54299: Improper Input Validation

Astro is a web framework. Prior to 6.4.6, Astro SSR apps with prerendered error pages /404 or /500 using export const prerender = true fetch those pages over HTTP at runtime when an error occurs. The URL for this fetch is derived from request.url, which in turn gets its origin from the incoming...

CVE-2026-49468: Authentication Bypass by Spoofing

LiteLLM is a proxy server AI Gateway to call LLM APIs in OpenAI or native format. Prior to 1.84.0, a Host-header parsing flaw in the LiteLLM proxy could, under specific conditions, allow unauthenticated access to protected management routes. The auth layer derived the effective route from...

Authentication Bypass

LiteLLM is vulnerable to Authentication Bypass. The vulnerability is due to improper Host header parsing during route validation, where the authentication layer derives the effective route from Host-influenced request metadata and may evaluate a different route than the one processed by FastAPI,...

Improper Request Routing

http-proxy-middleware is vulnerable to improper request routing. The vulnerability is due to unanchored substring matching in the host+path router selector logic, where configured host+path entries are matched against attacker-controlled request metadata using partial string comparisons instead o...
