CVE-2026-32277Network attack vector

Authenticated script execution via unsafe innerHTML rendering

Published Mar 23, 2026 · Updated Mar 23, 2026

DOM XSS in the Connect-CMS Cabinet Plugin in 1.35.0 through 1.41.0 and 2.35.0 through 2.41.0 allows remote authenticated users to run script. The Cabinet Plugin list view assigned saved names to selectedList.innerHTML by interpolating each name into an li element instead of treating the name as text. Exploitation requires access to the feature as an authenticated user and a victim to view the affected list, enabling browser-context actions or information theft.
