CVE-2026-8885

MEDIUM

DeMomentSomTres Shortcodes <= 1.1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

Title source: cna
STIX 2.1

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.
