An attacker who controls the Grid configuration can therefore supply child entries whose keys name event handlers, and those handlers execute in the origin of the page hosting the Grid. Custom icons take precedence over the built-in ones, so the attacker can replace icons that render without any further configuration, such as the sort icon shown in every column header by default and the pagination controls where pagination is enabled, and does not need any reference to a custom icon name. Exploitation requires that untrusted data reach the Grid configuration and that a user hover over or activate an affected icon.\n\n### Workarounds\nIf your Grid configuration comes from a source you do not fully control, paste this snippet right after importing the Grid module:\n\n```ts\n(function () {\n    const GridNS = typeof Grid !== 'undefined' ? Grid : undefined;\n    const G","public_affected_ranges":[">= 2.3.0, <= 3.1.0"]}],"null_published_at":"2026-10-31T22:13:27.124Z","source_updated_at":"2026-10-28T19:55:46.000Z","source_disclosed_at":"2026-10-28T19:55:46.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:56:36.327Z"}],"next_cursor":null,"snapshot_revision":"42594"}
