The CVE record's CNA (TWCERT/CC) lists 4MOSAn Security Technology 4MOSAn GCB Doctor versions before 20260621 as affected. No release containing a fix is confirmed on record.

4MOSAn GCB Doctor developed by 4MOSAn Security Technology has a OS Command Injection vulnerability. Unauthenticated remote attackers can inject malicious commands through an unremoved ADOdb test page parameter, thereby executing arbitrary system commands on the server.

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 yes (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".

In CISA KEV no (CISA's KEV catalog) · Automatable yes (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 22× in last 7d / 176× 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.

Showing the most recent 100 of 339 refreshes on record for this CVE.

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. None are among the latest 100 rows. The 239 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-78211?
CVE-2026-78211 is a critical-severity vulnerability; its CVE record was published on August 24, 2026. 4MOSAn GCB Doctor developed by 4MOSAn Security Technology has a OS Command Injection vulnerability. Unauthenticated remote attackers can inject malicious commands through an unremoved ADOdb test page parameter, thereby executing arbitrary system commands on the server.
When was the CVE record for CVE-2026-78211 published?
The CVE record for CVE-2026-78211 was published on August 24, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of October 12, 2026; the record at its source may have been updated since.
Is CVE-2026-78211 actively exploited?
CVE-2026-78211 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 2.0% probability of exploitation in the next 30 days (80th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-78211?
CVE-2026-78211 has a CVSS base score of 9.8 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-78211?
No fix for CVE-2026-78211 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (TWCERT/CC) lists 4MOSAn Security Technology 4MOSAn GCB Doctor versions before 20260621 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-78211 are linked in the Vendor Advisories panel on this page.
