CVE-2026-18894

Langflow OSS is affected by multiple vulnerabilities

6.5 MEDIUM
CVSS 3.1 · CNA

IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote attacker to trigger pre-existing stored Python component code in a public workflow, executing it under the flow owner's runtime context within the server process. This bypasses the intended trust boundary where public execution paths are restricted to server-trusted component code.
