CVE-2025-9075: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in bdthemes ZoloBlocks – Gutenberg Block Editor Plugin with Advanced Blocks, Dynamic Content, Templates & Patterns
The ZoloBlocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple Gutenberg blocks in versions up to, and including, 2.3.10. This is due to insufficient input sanitization and output escaping on user-supplied attributes within multiple block components including Google Maps markers, Lightbox captions, Image Gallery data attributes, Progress Pie prefix/suffix fields, and Text Path URL fields. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
The ZoloBlocks plugin for WordPress versions up to 2.3.10 suffers from stored cross-site scripting due to improper neutralization of input during web page generation (CWE-79). Multiple Gutenberg blocks, including Google Maps markers, Lightbox captions, Image Gallery data attributes, Progress Pie prefix/suffix fields, and Text Path URL fields, do not properly sanitize or escape user-supplied attributes. Authenticated attackers with contributor-level permissions or higher can inject arbitrary scripts that execute when other users access the compromised pages. This vulnerability can lead to information disclosure or session hijacking but does not impact availability.
Potential Impact
An attacker with contributor-level or higher access can inject malicious scripts into pages via vulnerable Gutenberg blocks. These scripts execute in the context of users viewing the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not affect system availability. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of vulnerable blocks. Monitor the vendor's communications for updates on patches or official mitigations.
