{"apiVersion":"1.0","identifier":"CVE-2026-54543","description":"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.","publishedAt":"2026-08-18T21:16:36","lastModifiedAt":"2026-08-19T13:17:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54543","cvssScore":5.4,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","epssProbability":0.00428,"riskScore":0.56,"affectedProduct":"Froxlor","affectedVersions":"<2.3.8","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-54543","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-54543","en":"https://www.redsauce.net/en/cves/CVE-2026-54543","fr":"https://www.redsauce.net/fr/cves/CVE-2026-54543","pt":"https://www.redsauce.net/pt/cves/CVE-2026-54543","de":"https://www.redsauce.net/de/cves/CVE-2026-54543","sk":"https://www.redsauce.net/sk/cves/CVE-2026-54543","el":"https://www.redsauce.net/el/cves/CVE-2026-54543"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-54543"}}
