Summary
IBM Langflow OSS (open-source software) versions 1.0.0 through 1.10.0 contains a critical security flaw in the `apply_tweaks()` function that allows authenticated users (those with login credentials) to override component parameters at runtime via the API (application programming interface, which lets software communicate with other software). This is a type of code injection vulnerability (where attackers insert malicious code by manipulating input that the system then executes).
