What is CVE-2026-41234?

Froxlor, an open-source server administration software, contains an input validation flaw in its DomainZones.add API endpoint prior to version 2.3.7. The vulnerability allows authenticated users with DNS editing privileges to inject newline characters into TXT record values. This improper sanitization can lead to a breakout in the record line of the generated BIND zone file, potentially enabling the injection of arbitrary BIND directives (such as $INCLUDE and $GENERATE) and unintended DNS records (A, MX, CNAME) in the stored zone file. This issue serves as an incomplete fix for an earlier vulnerability that addressed similar newline injections for other record types, indicating the need for diligent oversight and updates to mitigate such risks.
