Researcher István Márton - Wordfence

Description

The Skype Legacy Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'skype-status' shortcode in all versions up to, and including, 3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Wordfence blocked 1,342 attacks targeting this vulnerability in the past 24 hours.
