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

The CVE record's CNA (VulnCheck) lists Capgo versions before 12.128.2 as affected, and Capgo versions 12.128.2 as unaffected. No release containing a fix is confirmed on record.

Capgo before 12.128.2 contains a broken row level security policy in the org_users table that allows authenticated users to elevate privileges from admin to super_admin. Attackers can exploit the insufficient RLS enforcement to gain unauthorized super_admin access and compromise system security.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (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".

Data Freshness Timeline

(refreshed 11× in last 7d / 31× 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 209 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 109 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-56251?
CVE-2026-56251 is a medium-severity vulnerability; its CVE record was published on June 21, 2026. Capgo before 12.128.2 contains a broken row level security policy in the orgusers table that allows authenticated users to elevate privileges from admin to superadmin. Attackers can exploit the insufficient RLS enforcement to gain unauthorized super_admin access and compromise system security.
When was CVE-2026-56251 made public?
CVE-2026-56251 was made public on February 10, 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 June 21, 2026. EchelonGraph's copy of the record carries a last-modified date of June 22, 2026; the record at its source may have been updated since.
Is CVE-2026-56251 actively exploited?
CVE-2026-56251 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (36th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-56251?
CVE-2026-56251 has a CVSS base score of 6.5 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-56251?
No fix for CVE-2026-56251 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 Capgo versions before 12.128.2 as affected, and Capgo versions 12.128.2 as unaffected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-56251 are linked in the Vendor Advisories panel on this page.
