CVE-2026-61825Network attack vectorHinoki check available

Stored XSS via data-html-content sanitizer bypass

Published Sep 24, 2026 · Updated Sep 24, 2026

Stored XSS in Code16 Sharp before 9.22.5 allows remote authenticated users to execute script when another user views crafted editor content. SharpEditorFormField preserves executable markup when attacker-controlled content bears the data-html-content attribute, allowing it to survive storage and render later. Exploitation requires permission to store editor content and another user to view it; RAW_HTML content remains intentionally unsanitized by design.
