FKIE_CVE-2021-24522

Vulnerability from fkie_nvd - Published: 2021-08-09 10:15 - Updated: 2026-06-17 03:40
Severity
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
The User Registration, User Profile, Login & Membership – ProfilePress (Formerly WP User Avatar) WordPress plugin before 3.1.11's widget for tabbed login/register was not properly escaped and could be used in an XSS attack which could lead to wp-admin access. Further, the plugin in several places assigned $_POST as $_GET which meant that in some cases this could be replicated with just $_GET parameters and no need for $_POST values.
