Points Management System For Gamification, Ranks, Badges, and Loyalty Rewards Program – myCred <= 4.0.2 - Authenticated (Subscriber+) Arbitrary Shortcode Execution

The The Points Management System For Gamification, Ranks, Badges, and Loyalty Rewards Program – myCred plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 4.0.2. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Points Management System For Gamification, Ranks, Badges, and Loyalty Rewards Program 4.0.3 closes this, and updating the plugin is the step that ends it.
