Description

The ONLYOFFICE DocSpace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'onlyoffice-docspace' shortcode in all versions up to, and including, 2.1.1 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.

Affected products

ONLYOFFICE DocSpace: through 2.1.1
