This is due to the `get_item_permissions_check` method granting access to users with the `ssa_manage_appointments` capability without validating staff ownership of the requested appointment. This makes it possible for authenticated attackers, with custom-level access and above (users granted the ssa_manage_appointments capability, such as Team Members), to view appointment records belonging to other staff members and access sensitive customer personally identifiable information via the appointment ID parameter.","published":"2026-03-13T19:53:59.000Z","lastModified":"2026-06-17T10:16:22.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-639"],"affected":[],"epss":{"score":0.0022,"percentile":0.12425,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.22%).
