What is CVE-2026-1099?

The Administrative Shortcodes plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS). This vulnerability arises from inadequate input sanitization and output escaping in the 'login' and 'logout' shortcode attributes. Authenticated users with Contributor-level access or higher can exploit this flaw to inject arbitrary web scripts into pages. Consequently, these scripts will execute whenever another user accesses an affected page, creating potential security risks and compromising user data.
