[Security] Bump uvicorn from 0.11.3 to 0.11.7

[dependabot-preview]

Bumps uvicorn from 0.11.3 to 0.11.7. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Log injection in uvicorn This affects all versions of package uvicorn. The request logger provided by the package is vulnerable to ASNI escape sequence injection. Whenever any HTTP request is received, the default behaviour of uvicorn is to log its details to either the console or a log file. When attackers request crafted URLs with percent-encoded escape sequences, the logging component will log the URL after it's been processed with urllib.parse.unquote, therefore converting any percent-encoded characters into their single-character equivalent, which can have special meaning in terminal emulators. By requesting URLs with crafted paths, attackers can: * Pollute uvicorn's access logs, therefore jeopardising the integrity of such files. * Use ANSI sequence codes to attempt to interact with the terminal emulator that's displaying the logs (either in real time or from a file).

Affected versions: < 0.11.7

HTTP response splitting in uvicorn This affects all versions of package uvicorn. Uvicorn's implementation of the HTTP protocol for the httptools parser is vulnerable to HTTP response splitting. CRLF sequences are not escaped in the value of HTTP headers. Attackers can exploit this to add arbitrary headers to HTTP responses, or even return an arbitrary response body, whenever crafted input is used to construct HTTP headers.

Affected versions: < 0.11.7
