No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The Netdata web application through 1.13.0 allows remote attackers to inject their own malicious HTML code into an imported snapshot, aka HTML Injection. Successful exploitation will allow attacker-supplied HTML to run in the context of the affected browser, potentially allowing the attacker to steal authentication credentials or to control how the site is rendered to the user. NOTE: the vendor disputes the risk because there is a clear warning next to the button for importing a snapshot

Exploitation public PoC (EG-KEV: elevated) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
