Does this matter?

Lower severity and a low EPSS score (0.55%). Track it; it rarely justifies an emergency change on its own.

Description

The MainWP Child Reports plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 2.2.6. 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.
