CVE-2026-54283

Starlette is a lightweight ASGI framework/toolkit. From 0.4.1 until 1.3.1, request.form accepts maxfields and maxpartsize to bound resource consumption while parsing form data. These limits are enforced for multipart/form-data, but silently ignored for application/x-www-form-urlencoded. An...

CVE-2026-54282 Starlette: Unvalidated request path concatenated into authority poisons request.url.hostname

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...
