IBM Langflow OSS 1.0.0 through 1.9.6 contains a missing authentication vulnerability in /api/v1/build_public_tmp/ endpoints that allows an unauthenticated attacker to read build event data or cancel jobs using a valid job identifier, resulting in information disclosure and denial of service.
CVE-2026-10560
“—” beside the score: it is equal to NVD's CVSS score.
This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.5% (40th percentile of EPSS-scored CVEs). GitHub Security Advisory CVSS 8.2 is lower than this score; a lower GitHub score revises it only when its advisory is newer than the CVE record's last change, and this advisory (published 2026-06-30) is not newer than that change (2026-07-02), so it does not.
- High severity, but no confirmed exploitation yet
IBM strongly recommends addressing the vulnerability now by upgrading Langflow OSS to version 1.10.0 https://pypi.org/project/langflow/ (from the CVE record's solution, IBM Corporation) — apply it.

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 16× 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 100 of 350 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 250 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
