What the vulnerability does

01Description

The Social Media Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'twitter' shortcode in all versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Explanation of Vulnerability in Simple Terms

02Summary

Social Media Shortcodes versions 1.3.1 and earlier contain a cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, including administrators. The vulnerability affects the site's scope, meaning the injected code can interact with other parts of the site beyond the vulnerable component.
