Advisory
Source description from Wordfence Intelligence, credited to LVT-tholv2k.
The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.0.240 due to insufficient input sanitization and output escaping. 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.
