CVE-2026-75016: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wpblockart Magazine Blocks – Blog Designer, Magazine & Newspaper Website Builder, Page Builder with Posts Blocks, Post Grid
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.
AI Analysis
Technical Summary
CVE-2026-75016 is a stored cross-site scripting vulnerability in the Magazine Blocks plugin for WordPress, specifically in the News Ticker block's clientId attribute. The issue is caused by the NewsTicker::render() method concatenating the clientId attribute into an HTML class attribute without applying the esc_attr() function for proper escaping. This allows authenticated attackers with contributor or higher privileges to inject arbitrary web scripts that execute on page load.
Potential Impact
An attacker with contributor-level access or higher can inject malicious scripts into pages via the vulnerable clientId attribute. These scripts execute in the context of any user who views the infected page, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not require user interaction beyond viewing the page and does not impact availability.
Mitigation Recommendations
No official patch or fix is currently documented. Users should monitor the vendor's advisory for updates. Until a fix is available, restrict contributor-level access to trusted users only and consider removing or disabling the News Ticker block if feasible to reduce exposure.
