An operator allowed to use the REST API can cause the Authoritative server to produce invalid HTTPS or SVCB record data, which can in turn cause LMDB database corruption, if using the LMDB backend.

A rogue primary server may cause file descriptor exhaustion and eventually a denial of service, when a PowerDNS secondary server forwards a DNS update request to it.

Incomplete escaping of LDAP queries when running with 8bit-dns enabled allows users to perform queries of internal domain subtrees.

An attacker can send a notify request that causes a new secondary domain to be added to the bind backend, but causes said backend to update its configuration to an invalid one, leading to the backend no longer able to run on the next restart, requiring manual operation to fix it.

CVE-2026-33260 is a medium severity vulnerability in PowerDNS Authoritative versions 4.9.0 and 5.0.0. It allows an attacker to send a web request that triggers unlimited memory allocation in the internal web server, potentially causing a denial of service. The internal web server is disabled by default, which reduces the attack surface. There is no official patch or remediation level currently provided. No known exploits are reported in the wild.
