Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Highcharts Grid (the @highcharts/grid-lite and @highcharts/grid-pro npm packages, versions from 2.0.0 before 3.2.0) writes pagination language strings into the page as markup instead of plain text. An attacker who can control those language options and get untrusted data into the Grid language configuration, with pagination enabled, could run script in the origin of the hosting page when the pagination controls render. Upgrade both packages to 3.2.0 or later; the source also gives a workaround to run once after loading the Grid, before creating any grid.
