      "value": "Froxlor is open source server administration software. Prior to version 2.3.7, the `DomainZones.add` API endpoint does not sanitize newline characters in TXT record content. An authenticated customer with DNS editing enabled can inject newlines into TXT record values, which break out of the record line in the generated BIND zone file. This enables injection of arbitrary BIND directives (`$INCLUDE`, `$GENERATE`) and arbitrary DNS records (A, MX, CNAME) into the zone file written to disk by the DNS rebuild cron. This is an incomplete fix for CVE-2026-30932 (GHSA-x6w6-2xwp-3jh6), which patched the same newline injection for LOC, RP, SSHFP, and TLSA record types but did not patch TXT records. Version 2.3.7 contains an updated patch."

      "value": "Froxlor es un software de administración de servidores de código abierto. Antes de la versión 2.3.7, el endpoint de la API 'DomainZones.add' no sanitiza los caracteres de nueva línea en el contenido de los registros TXT. Un cliente autenticado con la edición de DNS habilitada puede inyectar nuevas líneas en los valores de los registros TXT, lo que rompe la línea del registro en el archivo de zona BIND generado. Esto permite la inyección de directivas BIND arbitrarias ('$INCLUDE', '$GENERATE') y registros DNS arbitrarios (A, MX, CNAME) en el archivo de zona escrito en disco por el cron de reconstrucción de DNS. Esta es una solución incompleta para CVE-2026-30932 (GHSA-x6w6-2xwp-3jh6), que parcheó la misma inyección de nueva línea para los tipos de registro LOC, RP, SSHFP y TLSA, pero no parcheó los registros TXT. La versión 2.3.7 contiene un parche actualizado."
