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...

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...

Starlette: Unvalidated request path concatenated into authority poisons request.url.hostname

Summary In affected versions, 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 @google.com moves the authority boundary...

GHSA-JP82-JPQV-5VV3 Starlette: Unvalidated request path concatenated into authority poisons request.url.hostname

Name of the Vulnerable Software and Affected Versions starlette versions prior to 1.3.1 Description The HTTP request path is not validated before being used to reconstruct request.url. When a path does not begin with /, such as @google.com, it is concatenated as scheme://hostpath. This shifts the...

CVE-2026-42517

This vulnerability exists in e-Sushrut due to the use of reversible Base64 encoding for protecting sensitive data. An authenticated attacker could exploit this vulnerability by decoding and manipulating Base64-encoded parameters in the request URL to gain unauthorized access to sensitive...

GHSA-86QP-5C8J-P5MR Starlette has missing Host header validation that poisons request.url.path, bypassing path-based security checks

Summary In affected versions, 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 could make request.url.path differ from the pa...

CVE-2026-48710

HTTP Request Smuggling

Overview starlette is a The little ASGI library that shines. Affected versions of this package are vulnerable to HTTP Request Smuggling via the request.url reconstruction process. An attacker can bypass path-based security checks by supplying a malformed Host header that causes request.url.path t...

CVE-2026-48710

Starlette (Python ASGI framework) contains a Host header validation issue in versions before 1.0.1. The HTTP Host header was not validated when reconstructing request.url, while routing relies on the raw path and request.url, allowing a malformed Host header to make request.url.path differ from t...
