{"schema":"threatline.record/2","record":{"id":"CVE-2026-103380","aliases":[],"summary":"Appointment Booking Plugin <= 5.7.3 - Authenticated (Subscriber+) Sensitive Information Exposure in 'first_name' Parameter Template Re-expansion","details":"The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.7.3 via the 'params[customer][first_name]' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract privileged booking data including the administrator-only admin_notes field, assigned agent internal contact details, transaction tokens, and payment request URLs delivered via rendered notification emails. A LatePoint customer can exploit this by storing a template placeholder such as {{customer_admin_notes}} in their own first_name field via the customer_cabinet__update route, then triggering the password-reset email flow to receive the expanded value in the resulting notification.","categories":["Applications & CMS"],"product":"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress","vendor":"latepoint","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103380","source_modified_at":"2026-10-15T16:43:49.346Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress","vendor":"latepoint","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.7.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0031,"percentile":0.22683,"score_date":"2026-10-23"},"published_at":"2026-10-14T07:43:32.242Z","modified_at":"2026-10-15T16:43:49.346Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-103380","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T16:43:49.346Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103380","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4494960c-66ed-47d9-b3fc-5a5ec5a07b1f?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/replacer_helper.php#L278"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/replacer_helper.php#L614"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/customer_cabinet_controller.php#L321"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/models/customer_model.php#L388"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/mailers/customer_mailer.php#L33"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3728691%40latepoint&new=3728691%40latepoint"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T10:52:24.378589Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-15T16:43:49.346Z","content_hash":"cd4c9634654118f94325cbf61e5b2421b564c25dd9b8936aa2e1ccee256fac9b"}}
