| CVE-2024-47874 | Hig | 0.50 | — | 0.01 | Oct 15, 2024 | Starlette is an Asynchronous Server Gateway Interface (ASGI) framework/toolkit. Prior to version 0.40.0, Starlette treats `multipart/form-data` parts without a `filename` as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload… | ||
| CVE-2026-54283 | Hig | 0.42 | 7.5 | 0.00 | Jun 22, 2026 | Starlette is a lightweight ASGI framework/toolkit. From 0.4.1 until 1.3.1, request.form() accepts max_fields and max_part_size to bound resource consumption while parsing form data. These limits are enforced for multipart/form-data, but silently ignored for… | ||
| CVE-2026-48818 | Hig | 0.42 | 7.5 | 0.00 | Jun 17, 2026 | Starlette is a lightweight ASGI framework/toolkit. In versions 1.0.1 and earlier, StaticFiles on Windows is vulnerable to SSRF. An UNC path such as \\attacker.com\share can cause os.path.realpath to initiate an outbound SMB connection before the path is rejected, exposing the… | ||
| CVE-2025-62727 | Hig | 0.42 | 7.5 | 0.01 | Oct 28, 2025 | Starlette is a lightweight ASGI framework/toolkit. Starting in version 0.39.0 and prior to version 0.49.1 , an unauthenticated attacker can send a crafted HTTP Range header that triggers quadratic-time processing in Starlette's FileResponse Range parsing/merging logic. This… | ||
| CVE-2026-48710 | Med | 0.35 | 6.5 | 0.02 | May 26, 2026 | 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`… | ||
| CVE-2026-48817 | Med | 0.27 | 5.3 | 0.00 | Jun 17, 2026 | Starlette is a lightweight ASGI framework/toolkit. In versions 1.0.1 and below, when dispatching a request, HTTPEndpoint selects the handler by lowercasing the HTTP method and looking it up as an attribute with getattr, without restricting the lookup to a known set of HTTP… | ||
| CVE-2025-54121 | Med | 0.27 | 5.3 | 0.01 | Jul 21, 2025 | Starlette is a lightweight ASGI (Asynchronous Server Gateway Interface) framework/toolkit, designed for building async web services in Python. In versions 0.47.1 and below, when parsing a multi-part form with large files (greater than the default max spool size) starlette will… | ||
| CVE-2026-54282 | Low | 0.17 | 3.7 | 0.00 | Jun 22, 2026 | 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… |
