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-2026-54282

The CVE concerns Starlette prior to 1.3.0: HTTP request path is not validated when reconstructing request.url, allowing attacker-controlled hostname by re-parsing a non-absolute path (e.g., @google.com). The issue is fixed in 1.3.0. Remediate by upgrading to 1.3.0+; no exploitation details are pr...

CVE-2026-48710

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...

CVE-2026-48710 Starlette has missing Host header validation that poisons request.url.path, bypassing path-based security checks

Starlette is a lightweight ASGI framework/toolkit. Prior to version 1.0.1, the HTTP Host request header was not validated before being used to reconstruct request.url. Because the routing algorithm relies on the raw HTTP path while request.url is rebuilt from the Host header, a malformed header...

Starlette , a lightweight Python ASGI framework, is vulnerable to a Host header injection that allows bypass of path-based security restrictions. Prior to version 1.0.1 , the HTTP Host request header was not validated before being used to reconstruct request.url, so a malformed header could make ...
