{"schemaVersion":3,"id":"CVE-2026-102291","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.3.1 This is due to the plugin substituting a user's `display_name` into the composed page markup unfiltered and then running the whole result through `do_shortcode()` in `TheFrontend::replace_content()`. Because `display_name` is writable by any user on their own account through the core profile form, this makes it possible for authenticated attackers with Subscriber-level access and above to execute arbitrary shortcodes. Where the page is a users collection — an ordinary team or member-directory page — the shortcode runs in the request of every visitor, including unauthenticated ones. Requires a published page with a Kirki element whose dynamic content is bound to the `display_name` user field.","dates":{"published":"2026-10-10T07:41:47.748Z","modified":"2026-10-11T16:55:15.382Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.4,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00304,"percentile":0.21782,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-10T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00304,"percentile":0.21782}],"last30":[{"date":"2026-10-10T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00304,"percentile":0.21782}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-74","name":"Improper
