This is due to the process_step_customer() function using is_user_logged_in() as the sole gate before merging POSTed customer data into an existing LatePoint customer, without any ownership checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the personal information (first name, last name, email, phone, notes) of arbitrary LatePoint customers, and, when the contact_merge setting is 'phone', to overwrite the victim's email address and take over the account via a password reset.","state":0,"publishedAt":"2026-10-07T23:27:12.424+00:00","modifiedAt":"2026-10-10T02:50:49.302+00:00","affected":[{"ecosystem":"Vendor product","name":"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"latepoint\",\n                    \"product\": \"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.6.9\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/83cdc51f-b5e1-42b9-972a-7e781f97b43e?source=cve","https://plugins.trac.wordpress.org/changeset/3631493/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-17538","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-17538","identifiers":["CVE-2026-17538"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
