CVE-2026-41234Public exploitNetwork attack vector

DNS record injection via TXT newline breakout

Published Jun 4, 2026 · Updated Jun 4, 2026

Injection in the DomainZones.add API endpoint in Froxlor before 2.3.7 allows remote authenticated users to alter BIND zone files. TXT content receives quote handling but no newline sanitization, so DnsEntry writes embedded lines as BIND directives or additional records. Exploitation requires customer access with DNS editing enabled and can disclose readable files, redirect DNS or mail traffic, or disrupt the affected zone.
