What it is

grist-core is a spreadsheet hosting server. A user visiting a malicious document and previewing an attachment could have their account compromised, because JavaScript in an SVG file would be evaluated in the context of their current page. This issue has been patched in version 1.3.2. Users are advised to upgrade. Users unable to upgrade should avoid previewing attachments in documents prepared by people they do not trust.
