CVE-2026-68582— Vikunja 授权问题漏洞

Vikunja 0.24.0 Broken Object Level Authorization via Link-Share Token

Vikunja versions >= 0.24.0 and <= 2.3.0 contain a broken object level authorization (BOLA) vulnerability in the task-collection endpoint (GET /api/v1/projects/{project}/views/{view}/tasks). The endpoint loads the requested project view from the URL path without verifying the caller is authorized for it. For a link-share token holder, the task scope is pinned to the share's own project, but the view is taken from the attacker-controlled path and never re-validated. As a result, a holder of any project share link can read any other tenant's kanban bucket records — bucket titles and the full created_by user object (username, name, id) — for every view in the instance. The same missing pre-authorization view load also creates a project/view-ID existence oracle (404 vs. non-404) usable by link shares and ordinary authenticated users. Task contents remain constrained to the share's own project and are not disclosed. Fixed in 2.4.0.

通过用户控制密钥绕过授权机制

Vikunja 授权问题漏洞

Vikunja是Vikunja团队开源的一个待办事项应用程序。 Vikunja 0.24.0版本至2.3.0版本存在授权问题漏洞，该漏洞源于任务收集端点从URL路径加载项目视图时未验证调用者是否被授权，导致对象级授权失效，链接共享令牌持有者可能读取其他租户的看板桶记录及用户信息。
