CVE-2026-75016 Details
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.
A stored cross-site scripting vulnerability has been identified in the Magazine Blocks plugin for WordPress, affecting versions through 1.8.6. The issue arises in the News Ticker block, where the clientId attribute is not properly sanitized before being output as part of an HTML class. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious scripts that are executed when users view the affected page.
Users are advised to update the Magazine Blocks plugin to version 1.8.7 or later, where this vulnerability has been patched.
