This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the 'list_readmore_numberofwords' Other Parameters setting to be configured with a positive integer value; the default value of 0 bypasses the decode-and-truncate branch entirely and is not exploitable through this sink.","state":0,"publishedAt":"2026-10-01T08:28:42.513+00:00","modifiedAt":"2026-10-01T14:13:25.726+00:00","affected":[{"ecosystem":"Vendor product","name":"Appointment Hour Booking – Booking Calendar","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"codepeople\",\n                    \"product\": \"Appointment Hour Booking – Booking Calendar\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.5.97\",\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:N/S:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3044e60f-b930-42db-ba5d-656e71b84226?source=cve","https://plugins.trac.wordpress.org/browser/appointment-hour-booking/tags/1.5.97/mv/js/jquery.calendar.js","https://plugins.trac.wordpress.org/browser/appointment-hour-booking/tags/1.5.97/cp-main-class.inc.php#L1473","https://plugins.trac.wordpress.org/browser/appointment-hour-booking/tags/1.5.97/cp-main-class.inc.php#L1609","https://plugins.trac.wordpress.org/browser/appointment-hour-booking/tags/1.5.97/cp-main-class.inc.php#L1745","https://plugins.trac.wordpress.org/browser/appointment-hour-booking/tags/1.5.97/classes/cp-base-class.inc.php#L81","https://plugins.trac.wordpress.org/changeset?reponame=&old=3718725%40appointment-hour-booking&new=3718725%40appointment-hour-booking"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96573","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96573","identifiers":["CVE-2026-96573"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
