Why wavexis_overlay_highlight is rated High
This tool performs a browser automation action that modifies the visual state of the browser by drawing an overlay. It doesn't read data, write persistent data, or cause destructive/financial effects, but it does execute a browser operation. The blast radius is low since it only affects visual rendering temporarily.
