The CVE record's CNA (VulnCheck) lists stylefeng Guns versions up to and including 8.3.5 as affected. No release containing a fix is confirmed on record.

Guns through 8.3.5 contains an improper access control vulnerability in SysNoticeController where requiredPermission defaults to false and is not overridden by any action methods. Authenticated users without assigned roles can exploit this to create, edit, delete, publish and retract system-wide notices affecting arbitrary users and departments.

EG Risk 45/100

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.

How it’s computed (value × EchelonGraph’s weight)

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".

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.

Frequently asked(5)

What is CVE-2026-92601?
CVE-2026-92601 is a medium-severity vulnerability; its CVE record was published on September 16, 2026. Guns through 8.3.5 contains an improper access control vulnerability in SysNoticeController where requiredPermission defaults to false and is not overridden by any action methods. Authenticated users without assigned roles can exploit this to create, edit, delete, publish and retract system-wide…
When was CVE-2026-92601 made public?
CVE-2026-92601 was made public on June 18, 2026: that is the date its CVE record's CNA, VulnCheck, gives for when the vulnerability was made public. The CVE record itself was published on September 16, 2026. EchelonGraph's copy of the record carries a last-modified date of September 24, 2026; the record at its source may have been updated since.
Is CVE-2026-92601 actively exploited?
CVE-2026-92601 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (32nd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-92601?
CVE-2026-92601 has a CVSS base score of 6.5 (the CNA's own assessment, by vulncheck; NVD's own analysis pending).
How do I remediate CVE-2026-92601?
No fix for CVE-2026-92601 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 (VulnCheck) lists stylefeng Guns versions up to and including 8.3.5 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-92601 are linked in the Vendor Advisories panel on this page.
