Prior to 1.123.55, 2.25.7, and 2.26.2, a member-level user with editor access to a shared workflow could reference credentials they do not own via specific public API endpoints. Credential ownership checks were only enforced partially leading to cross-user credential access. This issue affects instances where workflow sharing is enabled and at least one workflow has been shared with a member-level user as an Editor.
