HIGH

JAY Login & Register <2.6.03 - Privilege Escalation

Title source: llm

Description

The JAY Login & Register plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.6.03. This is due to the plugin allowing a user to update arbitrary user meta through the 'jay_panel_ajax_update_profile' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator.
