Magazine Blocks – Blog Designer, Magazine & Newspaper Website Builder, Page Builder with Posts Blocks, Post Grid, CVE-2026-75016
- CVE, Research URL
- Published on
- Sep 18, 2026
- Research Description
- The Magazine Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the News Ticker block's clientId attribute in versions up to, and including, 1.8.6. This is due to insufficient input sanitization and output escaping in the NewsTicker::render() method, which concatenates the clientId block attribute into an HTML class attribute without applying esc_attr(). 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.
- Affected versions
-
max 1.8.7.
- Status
-
