EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
