CVE-2026-125392 · Severity: medium · CVSS 5.4 · Published 2026-11-10

Webmin is a web-based server management panel that administrators use to configure and monitor servers. The bind8 DNS management module contains a stored cross-site scripting vulnerability where DNS record values are displayed without HTML escaping, allowing delegated zone users (such as domain owners in Virtualmin) to inject malicious scripts that execute in an administrator's browser when viewing zone records.

## Technical details

The edit_recs.cgi script in the bind8 module outputs raw DNS record values without HTML entity encoding in ALL view mode. An attacker with delegated zone permissions can craft DNS records containing JavaScript payloads that persist in the zone file and execute in an administrator's browser session, potentially leading to session hijacking or administrative action takeover. A fix is available in newer versions.
