Stored script execution via unescaped power-feed names
Published Jul 9, 2024 · Updated Aug 2, 2024
Stored XSS in NetBox 4.0.3 allows remote authenticated users to execute script in another user's browser through a power-feed name. The power-feed edit path accepts a crafted Name value, stores it, and later renders the affected object attribute as a safe string without HTML escaping. The attacker needs permission to edit the field, and execution requires another user to open a web-interface view that displays the stored name.
