CVE-2026-2602: Twentig Plugin for WordPress Allows Malicious Scripts to Run

CVE-2026-2602 · published 7 months ago

Summary

The Twentig plugin for WordPress has a security flaw that allows attackers to inject malicious code into certain pages. This could harm your website if an attacker has access to the site. Update the plugin to the latest version to fix the issue.

Original advisory text

The Twentig plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'featuredImageSizeWidth' parameter in versions up to, and including, 1.9.7 due to insufficient input sanitization and output escaping. 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.
