Users should monitor IBM advisories for updates and apply patches once released. In the meantime, restrict access to trusted users only and consider additional application-level controls to limit code injection risks.
Description
IBM Langflow OSS versions 1.0.0 through 1.12.3 contain a vulnerability that allows a remote authenticated attacker to execute arbitrary code. This is due to improper neutralization of special elements used in code, which can lead to code injection and execution.
