Vega allows Cross-site Scripting via the vlSelectionTuples function
Summary
Vega allows Cross-site Scripting via the vlSelectionTuples function
Original description
The description as published by the source.
Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. Prior to version 5.26.0 of vega and 5.4.2 of vega-selections, the vlSelectionTuples function can be used to call JavaScript functions, leading to cross-site scripting.vlSelectionTuples calls multiple functions that can be controlled by an attacker, including one call with an attacker-controlled argument. This can be used to call Function() with arbitrary JavaScript and the resulting function can be called with vlSelectionTuples or using a type coercion to call toString or valueOf. Version 5.26.0 of vega and 5.4.2 of vega-selections fix this issue.
