Description

All versions of SheetJS CE through 0.19.2 are vulnerable to "Prototype Pollution" when reading specially crafted files. Workflows that do not read arbitrary files (for example, exporting data to spreadsheet files) are unaffected.

A non-vulnerable version cannot be found via npm, as the repository hosted on GitHub and the npm package xlsx are no longer maintained.
