What is CVE-2025-9075?
CVE-2025-9075 is a medium-severity cross-site scripting vulnerability in bdthemes ZoloBlocks – Gutenberg Block Editor Plugin with Advanced Blocks, Dynamic Content, Templates & Patterns, published on 1 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
