What is CVE-2026-4895?

The GreenShift Animation and Page Builder Blocks plugin for WordPress is susceptible to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping within the gspb_greenShift_block_script_assets() function. When processing HTML string replacements for images, authenticated users with contributor-level access can inject arbitrary web scripts into page attributes. This occurs because the str_replace() function fails to properly parse the HTML, allowing the introduction of malicious JavaScript payloads. As a result, any user visiting the compromised page could unknowingly execute the injected scripts.

Affected Version(s)

Greenshift – animation and page builder blocks 0 <= 12.8.9
