High CVSS 7.4

CVE-2026-48079

NVD analysis in progress

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.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
Impact
An attacker can read sensitive data and modify or destroy data.
Weakness
Sessions do not expire quickly enough, so a stolen token stays valid for a long time.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle. Start with the instances exposed to the internet.
