Description

Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, Vikunjas scoped API token enforcement for custom project background routes is method-confused. A token with only projects.background can successfully delete a project background, while a token with only projects.background_delete is rejected. This is a scoped-token authorization bypass. This vulnerability is fixed in 2.3.0.
