Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. The WordPress, CMS and hosting-panel entries come from the National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan and others); we show who. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
