CM CSS Columns 1

Exploited only (KEV) →

CVE-2026-1098 Medium · 6.4 CWE-79 Jan 24, 2026

CM CSS Columns <= 1.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'tag' Shortcode Attribute

The CM CSS Columns plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tag' shortcode attribute in all versions up to, and including, 1.2.1 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.
