Description
CVE-2026-54543 is an injection vulnerability in Froxlor server administration software versions prior to 2.3.8. The DomainZones.add API command improperly accepts user-controlled record and type values containing line delimiters, tabs, semicolons, or unsupported DNS record types. This allows an authenticated user with DNS-zone permissions to inject additional resource-record lines into BIND zone files, potentially modifying DNS data and impacting DNS availability within authorized zones. The issue is fixed in Froxlor version 2.3.8.
