Questions about CVE-2026-104328
What does this mean?
A remote attacker who has already logged in can run arbitrary code on the Langflow OSS server. The advisory describes this as an authenticated remote code execution flaw.Source: ibm.com
Am I affected, and how do I check?
Langflow OSS versions 1.0.0 through 1.12.3 are affected. To check a install, look at the Langflow version it reports, for example in its package metadata or startup output.Source: ibm.com
What should I do about it?
Upgrade Langflow OSS to version 1.12.4, which IBM strongly recommends. The facts do not list a workaround.Source: ibm.com
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
