It reads this page and tells you if your code or app is affected.
Sites running the free WP Ultimate CSV Importer below 9.2 or the Pro version below 9.0.7 that have used the single post export feature. The exposure is through the public file location the export writes to, so sites that never used single post export are less likely to hold exposed files. Sites that do not run these plugins can skip it.
