Hi,
The following vulnerability was published for starlette.
CVE-2026-54282[0]:
| 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}://{host}{path} and re-parsing the result, a
| path that does not begin with / (for example @google.com) moves the
| authority boundary during re-parsing, so request.url.hostname and
| request.url.netloc become attacker-controlled. Code that reads
| request.url.hostname (rather than the Host header or scope) can
| therefore be misled into trusting an attacker-supplied host. This
| vulnerability is fixed in 1.3.0.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
