This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the targeted calendar to have more than 200 bookings, as the orderby value is only forwarded to the database layer when the AJAX handler takes the use_ajax branch; an Administrator can satisfy this condition by creating bookings directly.","published":"2026-10-16T07:17:12.000Z","lastModified":"2026-10-16T15:17:13.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-89"],"affected":[],"epss":{"score":0.00294,"percentile":0.21936,"date":"2026-10-27","history":[{"date":"2026-10-16","score":0.00294,"percentile":0.2063}]},"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 (0.29%).
