No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (Fsas Technologies) lists Fujitsu Linux openFT versions up to and including 12.1C96; Fujitsu Oracle Solaris openFT versions up to and including 12.1C95 as affected, and Fujitsu Linux openFT versions 12.1D00; Fujitsu Oracle Solaris openFT versions 12.1D00 as unaffected. No release containing a fix is confirmed on record.

A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for local privilege escalation to root of an already authenticated user on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and covers the CVE beyond its CNA scope under existing agreement with Fujitsu Germany.

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 9× in last 7d / 44× 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 213 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 113 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

CVE-2026-16607 is a high-severity vulnerability; its CVE record was published on July 22, 2026. A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for local privilege escalation to root of an already authenticated user on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and…
When was CVE-2026-16607 made public?
CVE-2026-16607 was made public on July 22, 2026: that is the date its CVE record's CNA, Fsas Technologies, gives for when the vulnerability was made public. The CVE record itself was published on July 22, 2026. EchelonGraph's copy of the record carries a last-modified date of July 22, 2026; the record at its source may have been updated since.
Is CVE-2026-16607 actively exploited?
CVE-2026-16607 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.1% probability of exploitation in the next 30 days (3rd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-16607?
CVE-2026-16607 has a CVSS base score of 7.8 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-16607?
No fix for CVE-2026-16607 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 (Fsas Technologies) lists Fujitsu Linux openFT versions up to and including 12.1C96; Fujitsu Oracle Solaris openFT versions up to and including 12.1C95 as affected, and Fujitsu Linux openFT versions 12.1D00; Fujitsu Oracle Solaris openFT versions 12.1D00 as unaffected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-16607 are linked in the Vendor Advisories panel on this page.
