Answer in brief
CVE-2026-54543 records a Medium severity (CVSS 5.4) vulnerability in Froxlor DomainZones.add allows DNS zone-file RR injection via record/type fields. The current sources do not mark it as known exploited. The current feed maps froxlor/froxlor (composer), froxlor/froxlor (generic), froxlor/froxlor (packagist). Check affected ranges and fixed versions before updating.

CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Froxlor is open source server administration software. Prior to 2.3.8, the DomainZones.add API command in lib/Froxlor/Api/Commands/DomainZones.php accepts user-controlled record and type values without rejecting line delimiters, tab characters, semicolons, or unsupported DNS record types before lib/Froxlor/Dns/DnsEntry.php serializes the values into a BIND zone file. An authenticated customer with DNS-zone permissions can place a crafted value in the record field, or use the related type-field variant, to create additional resource-record lines that bypass Froxlor's field-level validation. BIND accepts the injected records, allowing modification of DNS data and possible DNS availability impact within a zone the caller is authorized to manage. This issue is fixed in version 2.3.8.
