Description

The Share to Google Classroom plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the share_to_google shortcode in all versions up to, and including, 1.0 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.

Attack-Flow Graph

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Share to Google Classroom plugin for WordPress. It occurs via the share_to_google shortcode in all versions up to and including 1.0. The problem arises because the plugin does not properly sanitize or escape user-supplied attributes, allowing authenticated users with Contributor-level access or higher to inject malicious scripts. These scripts then execute whenever any user views the affected page.

Impact Analysis

An attacker with Contributor-level access or higher can exploit this vulnerability to inject arbitrary web scripts into pages. This can lead to unauthorized actions such as stealing user session data, defacing the website, or performing actions on behalf of other users without their consent. Since the scripts execute in the context of the affected site, it can compromise user data and site integrity.
