What is CVE-2026-54347?

Froxlor, an open-source server administration software, contains a vulnerability allowing authenticated users with DNS editor access to inject JavaScript code into DNS TXT records. This occurs because the software fails to properly sanitize input coming from the user. When an administrator views the DNS configuration of the affected domain, the injected JavaScript executes in their browser, which could potentially expose their session data or enable unauthorized actions. This issue has been addressed in Froxlor version 2.3.8.

Affected Version(s)
