FKIE_CVE-2026-8872

Vulnerability from fkie_nvd - Published: 2026-05-27 07:16 - Updated: 2026-05-27 14:50
Severity
6.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Summary
The Animate Your Content plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'animation-set' shortcode in versions up to, and including, 1.0.0. This is due to insufficient input sanitization and output escaping on user supplied attributes in the shortcode_args_to_html_attrs() function, which concatenates shortcode attribute values directly into double-quoted HTML attributes without calling 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.
