Deferred Deferred - Pending Action
Stored XSS in Dideo WordPress Plugin via Unsanitized Shortcode Attribute

Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: Wordfence

Description
The Dideo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'dideo' shortcode in version 1.0. This is due to insufficient input sanitization and output escaping on the 'id' shortcode attribute, which is interpolated directly into an HTML iframe 'src' attribute without escaping in the dideo() shortcode handler. 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.

Executive Summary

The Dideo plugin for WordPress version 1.0 has a Stored Cross-Site Scripting (XSS) vulnerability. This occurs because the plugin does not properly sanitize or escape the 'id' attribute of its 'dideo' shortcode. The 'id' value is directly inserted into an HTML iframe 'src' attribute without escaping, allowing authenticated users with contributor-level access or higher to inject malicious scripts. These scripts then execute whenever any user views the affected page.

Impact Analysis

This vulnerability can allow attackers with contributor-level access to inject arbitrary web scripts into pages. When other users access these pages, the malicious scripts execute in their browsers. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed in the context of the affected website.
