This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user (with Editor-level access or above, holding the manage_categories capability, or an Administrator) into performing an action such as clicking on a specially crafted link.","state":0,"publishedAt":"2026-10-28T07:48:29.075+00:00","modifiedAt":"2026-10-29T01:41:50.091+00:00","affected":[{"ecosystem":"Vendor product","name":"Echo Knowledge Base – Documentation, FAQs, Chat & Smart Search","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"echoplugins\",\n                    \"product\": \"Echo Knowledge Base – Documentation, FAQs, Chat & Smart Search\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"17.214.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3bfab9cf-4ccb-45fc-83ce-b5250f0f6482?source=cve","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/features/articles/class-epkb-articles-setup.php#L319","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/features/articles/class-epkb-articles-setup.php#L131","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/admin/editor/class-epkb-frontend-editor.php#L848","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/admin/editor/class-epkb-frontend-editor.php#L1072","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/class-epkb-utilities.php#L836","https://plugins.trac.wordpress.org/browser/echo-knowledge-base/tags/17.214.0/includes/features/layouts/class-epkb-layouts-setup.php#L45","https://plugins.trac.wordpress.org/changeset/3727663/echo-knowledge-base/trunk/includes/admin/editor/class-epkb-frontend-editor.php","https://plugins.trac.wordpress.org/changeset?reponame=&new=3727647%40echo-knowledge-base%2Ftags%2F17.311.0&old=3672811%40echo-knowledge-base%2Ftags%2F17.214.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-101935","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101935","identifiers":["CVE-2026-101935"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
