UpdraftPlus 1.22.14 to 1.23.2 and UpdraftPlus (Premium) 2.22.14 to 2.23.2 - Privilege Escalation via updraft_central_ajax_handler

Missing Authorization
CVSS 8.8 (High)
Publicly Published March 16, 2023
Last Updated March 17, 2023


The UpdraftPlus plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization on the 'updraft_central_ajax_handler' function in versions from 1.22.14 to 1.23.2 inclusive, and 2.22.14 to 2.23.2 of the premium version. This allows authenticated attackers, with subscriber-level permissions or above, to update the plugin's settings in such a way that can allow them to perform administrator-level actions on some sites.
