CVE-2025-57543 Details
Description
Cross Site scripting vulnerability (XSS) in NetBox 4.3.5 "comment" field on object forms. An attacker can inject arbitrary HTML, which will be rendered in the web UI when viewed by other users. This could potentially lead to user interface redress attacks or be escalated to XSS in certain contexts.
A cross-site scripting vulnerability has been identified in NetBox version 4.3.5. The issue arises in the 'comment' fields of various object forms, where user-supplied HTML is not properly sanitized. This allows attackers to inject arbitrary HTML that is rendered in the web interface for other users. While the injected HTML does not execute JavaScript directly, it could be used to manipulate the user interface or, in some cases, escalate to a more severe cross-site scripting attack.
