Title
waooAI waoowaoo Internal Task Header api-auth.ts requireProjectAuthLight improper authentication
Summary
A weakness has been identified in waooAI waoowaoo up to 0.4.1. Affected by this vulnerability is the function getInternalTaskSession/getAuthSession/requireUserAuth/requireProjectAuth/requireProjectAuthLight in the library src/lib/api-auth.ts of the component Internal Task Header Handler. This manipulation of the argument x-internal-user-id request causes improper authentication. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
