The CVE record names the fixed release — apply it.

OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.6, the bootstrap challenge endpoint at /api/tenants/{id}/appointments/bootstrap-challenge issues a SHA-256 proof-of-work with difficulty=4 hex zeros, equivalent to 16 bits of work. Modern hardware solves this in under 200 milliseconds, providing essentially no friction against automated abuse of the patient booking flow. Proof-of-work is used in the booking flow as a rate-limiter for unauthenticated clients establishing tunnels and submitting appointments. At 16 bits of difficulty, the construct is decorative rather than effective. An attacker can solve PoW challenges as fast as the server can issue them, defeating the rate-limiting purpose. The handler also calls challengeThrottleService.checkThrottle(binding, "passkey"), but the binding includes attacker-controlled values (tunnelId, clientPublicKey, and optional emailHash). For each fresh attempt, the attacker can supply new values, producing a new throttle key and bypassing the per-binding accumulation. Practical abuse friction is therefore the PoW difficulty itself, not a stable per-IP or per-email server-side throttle. Version 1.0.6 fixes the issue.

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 public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (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".
