What is CVE-2026-125392?

Webmin version 2.670 is affected by a stored cross-site scripting vulnerability located in the bind8/edit_recs.cgi file. This vulnerability arises when raw DNS record values are output without proper HTML escaping in ALL view mode, allowing delegated zone users, such as Virtualmin domain owners, to store script-containing record values. When an administrator views these zone records, the embedded scripts execute in their browser, potentially compromising sensitive data and session tokens.

Affected Version(s)
