What is CVE-2026-8847?

The Dideo plugin for WordPress is susceptible to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping of user-defined attributes in its 'dideo' shortcode. This issue arises when the 'id' attribute is directly injected into an HTML iframe's 'src' attribute without proper escaping. As a result, authenticated users with contributor-level access or higher can insert arbitrary scripts, which may execute in the browsers of users viewing affected pages. This vulnerability highlights the importance of thorough input validation and output handling to maintain the integrity and security of WordPress sites.

Affected Version(s)
