CVE-2026-97019 Details
Description
The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'headline-*' Shortcode Attribute in all versions up to, and including, 1.1.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A Subscriber-level user can store a malicious shortcode in their biographical info field; because WordPress core's wp_filter_kses() only strips HTML tags and not shortcode syntax, and because AMP content sanitizers run before do_shortcode() processes the archive description, the synthesized markup is never post-sanitized.
A stored cross-site scripting vulnerability has been identified in the AMP for WP - Accelerated Mobile Pages plugin for WordPress, affecting all versions through 1.1.17. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when users access the compromised pages. Subscribers can exploit this by embedding malicious shortcodes in their biographical info, as WordPress's default sanitization only removes HTML tags, not shortcode elements. Furthermore, the AMP content sanitization occurs before the shortcodes are processed, leaving the injected scripts unfiltered and active on the site.
Users are advised to update the AMP for WP - Accelerated Mobile Pages plugin to version 1.1.18 or a later patched version.
