Bradyholt · Jquery Googleslides · CVE-2026-8866
**Name of the Vulnerable Software and Affected Versions**
jQuery googleslides plugin for WordPress versions prior to 1.4
**Description**
Stored Cross-Site Scripting occurs via the 'googleslides' shortcode. The issue stems from insufficient input sanitization and output escaping within the `googleslides handler()` function. Specifically, the function interpolates user-supplied attributes—`userid`, `albumid`, `authkey`, `imgmax`, `maxresults`, `random`, `caption`, `albumlink`, `time`, and `fadespeed`—directly into single-quoted HTML attributes without utilizing `esc attr()`. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which execute when a user visits the affected page.
**Recommendations**
Update the jQuery googleslides plugin for WordPress to version 1.4 or later.
