Live › vulnerability › CVE-2026-48710
Go to dashboardStarlette builds the request URL from the Host header, so an attacker can inject path text into the host part and prepend it to the real path. If authentication checks the reconstructed URL path, the attacker can bypass it; the sources report this is chained with CVE-2026-42271 in LiteLLM for unauthenticated remote code execution.
