Summary
generated automatically from NVD dataIBM Langflow OSS versions 1.0.0 through 1.12.4 contain a code injection flaw (CWE-94) in how public workflows run component code. A remote attacker can trigger pre-existing stored Python component code in a public workflow, which then executes under the flow owner's runtime context inside the server process. This bypasses the trust boundary that limits public execution paths to server-trusted components, and the issue is rated 6.5 (MEDIUM, CVSS v3.1).
NVD description
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.
