{"id":"CVE-2026-55095","state":"PUBLISHED","title":"OpenProject: Inplace-edit dialog exposes comments from hidden admin-only project custom fields","description":"OpenProject is open-source, web-based project management software. In version 17.5.1 and earlier, an authenticated non-admin project member can request the inplace-edit dialog for a raw custom_field_ project attribute. The dialog path resolves the project custom field by its raw identifier without enforcing the normal admin_only visibility scope and renders the stored custom-field comment in read-only mode. This discloses hidden comment text but does not disclose the custom-field value or permit writes or mutation.
