Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Code Injection: Attackers can supply specially crafted string parameters containing unescaped double quotes or backslashes to break out of string boundaries in generated parameter cells, leading to arbitrary code execution inside the notebook environment.

Information Disclosure: Execution metadata previously captured and embedded the running environment's variables directly into the notebook structure, potentially exposing sensitive API keys and credentials to anyone with access to the generated notebook.
