The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the gspb_make_proxy_api_request() function in versions 11.4 to 11.4.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The arbitrary file upload was sufficiently patched in 11.4.5, but a capability check was added in 11.4.6 to properly prevent unauthorized limited file uploads.
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in wpsoul Greenshift greenshift-animation-and-page-builder-blocks allows Stored XSS.This issue affects Greenshift: from n/a through <= 10.8.
The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Authenticated (Subscriber+) Server-Side Request Forgery and Stored Cross Site Scripting in all versions up to, and including, 9.0.0 due to a missing capability check in the greenshift_download_file_localy function, along with no SSRF protection and sanitization on uploaded SVG files. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application that can also be leveraged to download malicious SVG files containing Cross-Site Scripting payloads to the server. On Cloud-based servers, attackers could retrieve the instance metadata. The issue was partially patched in version 8.9.9 and fully patched in version 9.0.1.
The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 9.9.9.3 via the 'wp_reusable_render' shortcode due to insufficient restrictions on which posts can be included. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from password protected, private, or draft posts that they should not have access to.
