CVE-2025-57543Public exploitNetwork attack vector

Interface manipulation via unescaped object comments

Published Mar 16, 2026 · Updated Mar 16, 2026

Stored HTML injection in NetBox 4.3.5 comment fields allows attackers to alter pages shown to users through crafted object comments. The object-comment template and generic view render stored comment input without sanitizing or escaping user-supplied HTML. An attacker must be able to submit an object comment, and another user must view the object; demonstrated impact is interface manipulation or phishing-style redirection, not direct script execution.
