Details

Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. In Vega prior to version 6.2.0, applications meeting 2 conditions are at risk of arbitrary JavaScript code execution, even if "safe mode" expressionInterpreter is used. They are vulnerable if they use vega in an application that attaches vega library and a vega.View instance similar to the Vega Editor to the global window and if they allow user-defined Vega JSON definitions (vs JSON that was is only provided through source code). Patches are available in the following Vega applications. If using the latest Vega line (6.x), upgrade to vega 6.2.0 / vega-expression 6.1.0 / vega-interpreter 2.2.1 (if using AST evaluator mode). If using Vega in a non-ESM environment, upgrade to vega-expression 5.2.1 / 1.2.1 (if using AST evaluator mode). Some workarounds are available. Do not attach vega View instances to global variables, and do not attach vega to the global window. These practices of attaching the vega library and View instances may be convenient for debugging, but should not be used in production or in any situation where vega/vega-lite definitions could be provided by untrusted parties.
