Description

Donetick an open-source app for managing tasks and chores. Prior to version 0.1.44, the application uses JSON Web Tokens (JWT) for authentication, but the signing secret has a weak default value.

This issue can result in full account takeover of any user. Version 0.1.44 contains a patch.
