Описание
JupyterHub has Unauthenticated Denial of Service via Unbounded Username Logging on Failed Login
Impact
Invalid input to login resulted in unbounded logging output. Only form-based Authenticators (the default PAM Authenticator, but not the more widely used OAuthenticator) are affected.
Patches
Upgrade to 5.5.0.
Workarounds
Use an Authenticator that doesn't use a login form, such as OAuthenticator.

JupyterHub is software that allows users to create a multi-user server for Jupyter notebooks. Prior to 5.5.0, invalid input to form-based login authenticators can place an unbounded attacker-controlled username in failed-login logs, allowing an unauthenticated attacker to consume logging and storage resources. This issue is fixed in version 5.5.0.
