What is CVE-2026-30236?

OpenProject, a web-based project management software, exhibited a vulnerability that allowed unauthorized users to access sensitive information regarding project member budgets and labor costs. Specifically, prior to version 17.2.0, the system failed to validate whether a user was indeed a member of a project when they attempted to edit budget-related details. This oversight could lead to unauthorized disclosure of user rate information and allow calculations involving budgets of non-members. The issue was addressed in version 17.2.0, reinforcing the need for strict membership checks in sensitive financial operations.
