Plugin greenshift-animation-and-page-builder-blocks
Severity Medium (CVSS 6.4)

Vulnerable Version 12.8.9
Patched Version 12.9.0
Disclosed April 9, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-4895:
This vulnerability is an authenticated stored cross-site scripting (XSS) flaw in the GreenShift WordPress plugin versions up to 12.8.9. The vulnerability exists in the plugin’s block rendering function, allowing contributors and higher-privileged users to inject malicious scripts that execute when pages load.

Root Cause:
The vulnerability originates in the gspb_greenShift_block_script_assets() function within the init.php file. When processing greenshift-blocks/image blocks with the disablelazy attribute enabled, the function performs a str_replace() operation on line 904. This operation replaces ‘src=’ with ‘fetchpriority=”high” src=’ directly on the raw HTML string without proper parsing. The str_replace() function operates on the entire HTML string, allowing attackers to inject ‘src=’ substrings within HTML attribute values. When the replacement occurs, the double quotes in the injected string break attribute context, enabling injection of malicious attributes like onfocus with JavaScript payloads.

Exploitation:
An authenticated attacker with contributor-level access or higher can exploit this vulnerability by creating or editing a post containing a greenshift-blocks/image block with the disablelazy attribute. The attacker injects malicious HTML containing ‘src=’ substrings within attribute values, such as in a class attribute. When the plugin processes the block, the str_replace() operation inserts ‘fetchpriority=”high”‘ before each ‘src=’ occurrence, including those within attribute values. This breaks the attribute context and allows injection of event handlers like onfocus=”alert(document.cookie)” that execute when users interact with the page.

Patch Analysis:
The patch replaces the vulnerable str_replace() approach with WordPress’s WP_HTML_Tag_Processor class. In the patched code at line 904-908, the plugin creates a new WP_HTML_Tag_Processor instance to parse the HTML, specifically targets img tags using next_tag(‘img’), and safely sets the fetchpriority attribute using set_attribute(). This proper HTML parsing prevents attribute context confusion. The patch also adds escaping to other str_replace() operations in the same function, such as lines 990-992 where id, openlabel, closelabel, and position parameters now use esc_attr().

Impact:
Successful exploitation allows attackers with contributor-level permissions to inject arbitrary JavaScript into pages. This JavaScript executes in the context of any user viewing the compromised page, potentially leading to session hijacking, account takeover, content defacement, or malware distribution. The stored nature means the payload persists across multiple page views without requiring further interaction from the attacker.
