Lifecycle Timeline
2Description
OpenProject is an open-source, web-based project management software. Prior to 17.2.0, when editing a project budget and planning the labor cost, it was not checked that the user that was planned in the budget is actually a project member. This exposed the user's default rate (if one was set up) to users that should only see that information for project members. Also, the endpoint that handles the pre-calculation for the frontend to display a preview of the costs, while it was being entered, did not properly validate the membership of the user as well. This also allowed to calculate costs with the default rate of non-members. This vulnerability is fixed in 17.2.0.
Analysis
OpenProject prior to 17.2.0 fails to validate project membership when calculating labor costs in budget planning, allowing authenticated users to enumerate non-member employees' default billing rates. This exposure occurs both when editing budgets directly and through the cost preview calculation endpoint, potentially revealing sensitive salary information to unauthorized project users.
