A fix is referenced (a reference tagged "Patch", often a source commit), but no release containing it is confirmed — find the release that contains it; until it is applied, mitigate (WAF / firewall / segmentation).

Affected versions of Flowintel expose the /my_assignment/user API endpoint to any authenticated API user. The endpoint accepts a user_id parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication.

As a result, a lower-privileged authenticated user could potentially query another user’s assignment information by supplying that user’s identifier.

The fix changes:

method_decorators = [api_required]

to:

method_decorators = [admin_or_org_admin_required, api_required]

so only administrators or organization administrators can perform cross-user assignment queries.

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 17× in last 7d / 78× 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 128 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 29 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-81819?
CVE-2026-81819 is a medium-severity vulnerability; its CVE record was published on August 27, 2026. Affected versions of Flowintel expose the /myassignment/user API endpoint to any authenticated API user. The endpoint accepts a userid parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication. As a result, a…
When was the CVE record for CVE-2026-81819 published?
The CVE record for CVE-2026-81819 was published on August 27, 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 August 28, 2026; the record at its source may have been updated since.
Is CVE-2026-81819 actively exploited?
CVE-2026-81819 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.5% probability of exploitation in the next 30 days (38th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-81819?
CVE-2026-81819 has a CVSS base score of 5.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-81819?
A fix for CVE-2026-81819 is referenced (a reference tagged "Patch", often a source commit), but EchelonGraph has no release containing it on record. Check that reference and the vendor's advisory for a release that contains the fix and update to it; until then, restrict network exposure of the affected system or apply the vendor's mitigation. The vendor advisories EchelonGraph has for CVE-2026-81819 are linked in the Vendor Advisories panel on this page.
