    "title": "OpenReception's logout page clears local access_token before server-side revocation, leaving duplicated tokens valid until expiry",
    "summary": "OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, when a user navigates to the `/logout` page, the page's server-side load handler deletes the `access_token` cookie before calling `/api/auth/logout` via an internal `event.fetch()`. The internal fetch consequently runs without the auth cookie, so `apiAuthHandle` rejects it, the logout handler never executes, and `SessionService.revokeSession()` is never called for the current session. The DB session row remains valid until its natural expiry (one week by default). The user sees a successful logout (cookie gone, UI returns to login), but any party still holding a copy of the now-deleted access token can continue making authenticated API calls until the session naturally expires. The root cause is a simple ordering mistake. The same auth subsystem implements the correct order in `/api/auth/logout`: revoke the current DB session first, then delete the cookie. The page-level wrapper does the opposite. Version 1.0.2 initiates server-side logout before removing authentication cookies and first appears in version 1.0.2. Version 2.0.0 later replaces this with a race-free client-side logout flow.",
