CVE-2026-6255 Medium · 6.4 CWE-79 May 5, 2026

Simple Owl Shortcodes <= 2.1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'num' Shortcode Attribute

The Simple Owl Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'num' attribute of the 'owls_wrapper' shortcode in all versions up to, and including, 2.1.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
