{"id":"CVE-2026-41230","state":"PUBLISHED","title":"Froxlor has a BIND Zone File Injection via Unsanitized DNS Record Content in DomainZones::add()","description":"Froxlor is open source server administration software. Prior to version 2.3.6, `DomainZones::add()` accepts arbitrary DNS record types without a whitelist and does not sanitize newline characters in the `content` field. When a DNS type not covered by the if/elseif validation chain is submitted (e.g., `NAPTR`, `PTR`, `HINFO`), content validation is entirely bypassed. Embedded newline characters in the content survive `trim()` processing, are stored in the database, and are written directly into BIND zone files via `DnsEntry::__toString()`. An authenticated customer can inject arbitrary DNS records and BIND directives (`$INCLUDE`, `$ORIGIN`, `$GENERATE`) into their domain's zone file. Version 2.3.6 fixes the issue.","publishedAt":"2026-04-23T03:47:11.258Z","updatedAt":"2026-04-23T13:58:27.592Z","severity":{"score":8.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["froxlor froxlor"],"affected":[{"vendor":"froxlor","product":"froxlor","versions":[{"version":"< 2.3.6","status":"affected"}]}],"references":["https://github.com/froxlor/froxlor/security/advisories/GHSA-47hf-23pw-3m8c","https://github.com/froxlor/froxlor/commit/47a8af5d9523cb6ec94567405cfc2e294d3a1442","https://github.com/froxlor/froxlor/releases/tag/2.3.6"],"weaknesses":["CWE-93"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41230.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41230","state":"PUBLISHED","datePublished":"2026-04-23T03:47:11.258Z","dateUpdated":"2026-04-23T13:58:27.592Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-18T03:47:03.134Z"},"containers":{"cna":{"title":"Froxlor has a BIND Zone File Injection via Unsanitized DNS Record Content in DomainZones::add()","descriptions":[{"lang":"en","value":"Froxlor is open source server administration software.
