Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Wpsoul Greenshift – animation and page builder blocks allows Stored XSS.This issue affects Greenshift – animation and page builder blocks: from n/a through 9.3.7.

The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation on the 'gspb_save_files' function in versions up to, and including, 7.6.2. This makes it possible for authenticated attackers with administrator-level capabilities or above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Auth. (author+) Cross-Site Scripting (XSS) vulnerability in Wpsoul Greenshift – animation and page builder blocks plugin <= 4.9.9 versions.

The Greenshift WordPress plugin before 5.0 does not validate and escape some of its block options before outputting them back in a page/post where the block is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

The Greenshift WordPress plugin before 4.8.9 does not validate and escape one of its shortcode attributes, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attack.
