This makes it possible for unauthenticated attackers to create approved bookings against services explicitly restricted to admins and agents, consuming restricted appointment capacity and triggering unauthorized bookings for admin/agent-only services. The bypass works via both the params[booking][service_id] parameter in steps__load_step and the presets[selected_service] parameter in steps__start, both of which are publicly accessible without authentication.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/latepoint/tags/5.3.2/lib/controllers/steps_controller.php#L244","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.3.2/lib/controllers/steps_controller.php#L341","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.3.2/lib/helpers/steps_helper.php#L1202","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.3.2/lib/helpers/steps_helper.php#L1618","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.3.2/lib/helpers/steps_helper.php#L1710"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-12657","score":0.00671,"percentile":0.52036,"date":"2026-10-31"},"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).
