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 12× in last 7d / 35× 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 99 of 201 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. 1 repeat row among the latest 100 is merged into the row it repeats. The 102 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Dell PowerScale OneFS versions 9.5.0.0 through 9.10.1.7, versions 9.11.0.0 through 9.13.0.2 contains an Insertion of Sensitive Information into Log File vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information disclosure.
When was CVE-2026-40633 made public?
CVE-2026-40633 was made public on June 30, 2026: that is the date its CVE record's CNA, Dell, gives for when the vulnerability was made public. The CVE record itself was published on July 15, 2026. EchelonGraph's copy of the record carries a last-modified date of July 15, 2026; the record at its source may have been updated since.
Is CVE-2026-40633 actively exploited?
CVE-2026-40633 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.2% probability of exploitation in the next 30 days (4th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-40633?
CVE-2026-40633 has a CVSS v3 base score of 5.5 (NVD). EchelonGraph synthesises NVD + CISA KEV + FIRST EPSS + GHSA into a combined EG score of 7.8 (HIGH).
How do I remediate CVE-2026-40633?
No fix for CVE-2026-40633 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 description, written by its CNA (Dell), states the affected versions: "Dell PowerScale OneFS versions 9.5.0.0 through 9.10.1.7, versions 9.11.0.0 through 9.13.0.2 contains an Insertion of Sensitive Information into Log File vulnerability." No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-40633 are linked in the Vendor Advisories panel on this page.
