Description

The Algori PDF Viewer plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to the use of a vulnerable version of pdf.js in all versions up to, and including, 1.0.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
