Vikunja: Any user can enumerate every team and its members by attaching arbitrary teams to a throwaway project

Summary When you share a project with a team, the API lets you attach any team on the instance, including teams you have nothing to do with, as long as you're an admin of the project. Listing a project's teams then returns each team's full member roster. So any logged-in user can spin up a...

Vikunja: Cross-tenant task-position rows can be injected into arbitrary project views via the unvalidated project_view_id in the task position endpoint (v1 and v2)

Summary The task-position endpoint authorizes only the task side of the write: TaskPosition.CanUpdate delegates to Task.CanUpdate write access to the task's own project and the request body's projectviewid is never validated to belong to the task's project, nor is any access to that view required...

Vikunja: Read-only project members can obtain any link share's access hash via the single-share read endpoint (v1 and v2) and escalate to the share's permission level

Summary A user who has only read permission on a project can call the single link-share read endpoint and receive the share's hash field — the secret credential that the anonymous POST /shares/share/auth endpoint exchanges for a link-share JWT carrying the share's permission read / read-write /...

Vikunja: Every /api/v2 pre-auth endpoint is unthrottled on a stock install while its /api/v1 twin is rate limited

Summary registerAPIRoutesV2 never applies the unconditional pre-auth rate-limit floor unauthRateLimit to the v2 public routes — it passes that limiter only to /api/v2/ws — and otherwise relies on setupRateLimit, which registers nothing when ratelimit.enabled is false the default. So on a stock...
