This allows an \nAPI consumer to access information for all other events under the same \norganizer, even those they should not have access to.\n\n\nThese records contain information on the time and result of every ticket scan as well as the ID of the matched ticket. Example:\n\n\n{\n  \"id\": 123,\n  \"successful\": true,\n  \"error_reason\": null,\n  \"error_explanation\": null,\n  \"position\": 321,\n  \"datetime\": \"2020-08-23T09:00:00+02:00\",\n  \"list\": 456,\n  \"created\": \"2020-08-23T09:00:00+02:00\",\n  \"auto_checked_in\": false,\n  \"gate\": null,\n  \"device\": 1,\n  \"device_id\": 1,\n  \"type\": \"entry\"\n}\n\n\n\nAn unauthorized user usually has no way to match these IDs (position) back to individual people.","published":"2026-04-08T13:16:44.000Z","lastModified":"2026-07-24T20:10:00.000Z","status":"Analyzed","sourceIdentifier":"655498c3-6ec5-4f0b-aea6-853b334d05a6","cvss":{"version":"4.0","score":5.5,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-653"],"affected":["pretix/pretix"],"epss":{"score":0.00255,"percentile":0.16975,"date":"2026-10-26","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 (0.26%).
