A fix is available — apply it.

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.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
