SA-CONTRIB-2015-071 – Simple Subscription – Cross Site Scripting (XSS)

Leave a comment

Description

This module enables you to add a block to allow visitors to subscribe to a site’s newsletter.

The module failed to sanitize some block content, leading to a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission “administer blocks”.
