Hi, The following vulnerability was published for python-uvicorn. CVE-2020-7694[0]: | 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). If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
