Upgrade to SoftIron HyperCloud 2.6.18 or later (from the CVE record's solution, SoftIron) — apply it.

Improper Neutralization of Special Elements used in a Command ('Command Injection') in the Orchestrator component of SoftIron HyperCloud allows an authenticated user with access to the management plane to execute arbitrary operating system commands on hypervisor hosts as the privileged orchestration user. Attacker-controlled virtual machine template content (for example, the VM DESCRIPTION field) is delivered to hosts through a shell here-document whose terminator is not quoted, so shell expansion and here-document terminator injection are performed on that content during virtual machine lifecycle operations such as deploy, migrate, and network setup. Exploitation requires valid credentials, access to the management plane (owning a virtual machine alone is not sufficient), and a lifecycle operation that reaches the affected host. This issue affects the Orchestrator component of SoftIron HyperCloud from 1.0 through 2.6.17 and is fixed in 2.6.18.

EG Risk 34/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

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".

The score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

Data Freshness Timeline

(refreshed 8× in last 7d / 20× 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 its CVE.org record (CNA or CISA ADP). 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). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.
