Questions about CVE-2026-104324
What does this mean?
The flaw is a deserialization issue in which untrusted data is processed unsafely, and a remote attacker with valid authentication could use it to execute arbitrary code on the Langflow server.Source: ibm.com
Am I affected, and how do I check?
The affected product is IBM Langflow OSS versions 1.0.0 through 1.12.3. To check an installed copy, compare its Langflow version against that range.Source: ibm.com
What should I do about it?
Upgrade IBM Langflow OSS to version 1.12.4, the fixed version named in the advisory.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
