This is due to a missing capability check in the heartbeat_received() function in the Live_Update class. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain MainWP Child Reports activity log entries (including action summaries, user information, IP addresses, and contextual data) via the WordPress Heartbeat API by sending a crafted heartbeat request with the 'wp-mainwp-stream-heartbeat' data key.","published":"2026-04-08T05:16:07.000Z","lastModified":"2026-07-24T20:10:00.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00545,"percentile":0.45562,"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 (0.55%).
