Product: Music Store
Exploit Author: Sachin Wagh
Version: 1.0.41
Home page Link: https://wordpress.org/plugins/music-store/
============================================================================
Details :
The Music Store plugin for WordPress is prone to a cross-site
scripting vulnerability because it fails to sufficiently sanitize
user-supplied input.
An attacker may leverage this issue to execute arbitrary script code
in the browser of an unsuspecting user in the context of the affected
site. This may allow the attacker to steal cookie-based authentication
credentials and to launch other attacks.
