Technical details

The POST /api/v2/oauth/authorize endpoint lacks authentication checks, permitting unauthenticated requests with client_id, redirect_uri, and approved=true parameters to generate valid authorization codes. Attackers can create unbounded ownerless authorization code records limited only by rate limiting, bypassing the OAuth approval flow. A fix is available in version 2026.08.0 and later.
