The CVE record names the fixed release — apply it.

Snipe-IT's predefined kit checkout path does not enforce Full Multiple Company Support (FMCS) tenant isolation on the checkout target. Unlike the single, bulk, API, accessory, license and consumable checkout paths, App\Services\PredefinedKitCheckoutService never calls $item->canCheckoutTo($target); it only performs the actor-vs-item policy check and an availability check before persisting the checkout. With FMCS enabled, a non-superuser who belongs to at least two companies and holds the assets.checkout permission can POST to /kits/{kit}/checkout with a user_id belonging only to company B and have a company-A asset (and likewise kit licenses, consumables and accessories) assigned to that user, bypassing the company-mismatch check that blocks the same operation on every other checkout path. The issue is fixed in Snipe-IT 8.7.2; it was runtime-verified on v8.6.3 and code-inspected on v8.7.1, and the affected service has lacked the check since 2019, so earlier FMCS deployments are likely also affected.

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".

Data Freshness Timeline

(refreshed 22× in last 7d / 85× in last 30d)

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). Most recent first.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 1 repeat row among the latest 95 is merged into the row it repeats.
