{"cve":"CVE-2026-11992","nvd":{"published":"2026-07-10T09:16:52.280","modified":"2026-07-10T15:43:30.330","status":"Deferred","description":"The Easy Appointments plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.12.27. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to cancel all upcoming appointments site-wide by marking every future appointment stored by the plugin as abandoned. The nonce required to authenticate the cancellation request is printed on the Appointments admin page, which is itself gated only by the edit_posts capability that Authors possess, making the nonce readily accessible to low-privileged users.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/easy-appointments/tags/3.12.24.1/src/ajax.php#L180","https://plugins.trac.wordpress.org/browser/easy-appointments/tags/3.12.24.1/src/ajax.php#L563","https://plugins.trac.wordpress.org/browser/easy-appointments/tags/3.12.24.1/src/ajax.php#L619","https://plugins.trac.wordpress.org/browser/easy-appointments/tags/3.12.24.1/src/templates/appointments.tpl.php#L302","https://plugins.trac.wordpress.org/browser/easy-appointments/tags/3.12.25/src/ajax.php#L180"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-11992","score":0.0046,"percentile":0.39904,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
