system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

    Uses Jinja2 for template. Injects Plotly JS for graph rendering.

    Example:

            body.
        header: if True, render experiment title as a header.
            Meant to be used for standalone reports (e.g. via email), as opposed
            to served on the front-end.
        offline: if True, entire Plotly library is bundled
            with report.
        notebook_env: if True, caps the report width to 700px for viewing in a
            notebook environment.
