CVE-2025-12661: Pollcaster Shortcode Plugin for WordPress allows attackers to inject malicious scripts

CVE-2025-12661 · published 11 months ago

Summary

The Pollcaster Shortcode Plugin for WordPress has a security flaw that allows someone with contributor-level or higher access to add malicious code to web pages. This code can be triggered when anyone visits the page, potentially harming the site or its visitors. Update to the latest version of the plugin to fix this issue.

Original advisory text

The Pollcaster Shortcode Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'height' parameter in the 'pollcaster' shortcode in all versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes. 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.
