Summary
IBM Langflow OSS from 1.0.0 through 1.12.3 is affected. Improper neutralization of special elements used in code (CWE-94) lets a remote authenticated attacker execute arbitrary code. The attacker needs low privileges, and exploitation requires no user interaction. Successful exploitation gives high impact to confidentiality, integrity and availability.
