  - Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive
    visualization designs. Prior to versions 6.1.2 and 5.6.3, applications meeting two conditions are at risk
    of arbitrary JavaScript code execution, even if safe mode expressionInterpreter is used. First, they use
    `vega` in an application that attaches both `vega` library and a `vega.View` instance similar to the Vega
    Editor to the global `window`, or has any other satisfactory function gadgets in the global scope. Second,
    they allow user-defined Vega `JSON` definitions (vs JSON that was is only provided through source code).
    This vulnerability allows for DOM XSS, potentially stored, potentially reflected, depending on how the
    library is being used. The vulnerability requires user interaction with the page to trigger. An attacker
    can exploit this issue by tricking a user into opening a malicious Vega specification. Successful
    exploitation allows the attacker to execute arbitrary JavaScript in the context of the application's
    domain. This can lead to theft of sensitive information such as authentication tokens, manipulation of
    data displayed to the user, or execution of unauthorized actions on behalf of the victim. This exploit
    compromises confidentiality and integrity of impacted applications.Patched versions are available in
    `[email protected]` (requires ESM) for Vega v6 and `[email protected]` (no ESM needed) for Vega
    v5. As a workaround, do not attach `vega` or `vega.View` instances to global variables or the window as
    the editor used to do. This is a development-only debugging practice that should not be used in any
    situation where Vega/Vega-lite definitions can come from untrusted parties. (CVE-2025-65110)

Note that Nessus relies on the presence of the package as reported by the vendor.");
