CVE-2026-8885

Description

The DeMomentSomTres Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin-s -callout- shortcode in all versions up to, and including, 1.1.1. This is due to insufficient input sanitization and output escaping on the -width- and -align- shortcode attributes within the st_callout() function, which concatenates the attribute values directly into an HTML style attribute. 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.
