Vulnerability Overview

The Namaste! LMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'accept_other_payment_methods', 'other_payment_methods' parameters in versions up to 2.5.9.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator-level access, and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 2.6, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
