CVE-2026-104317
IBM Langflow OSS 1.0.0 through 1.12.3 could allow a remote attacker who could reach the message broker to execute arbitrary code on the system due to the deserialization of untrusted data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
