CVE-2026-33260: Allocation of Resources Without Limits or Throttling in PowerDNS Authoritative
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 provided yet, and no known exploits in the wild have been reported. Users should verify if the internal web server is enabled in their deployments and monitor vendor advisories for updates.
AI Analysis
Technical Summary
This vulnerability involves allocation of resources without limits or throttling in the internal web server component of PowerDNS Authoritative. An attacker can send crafted web requests that cause the server to allocate memory indefinitely, leading to denial of service conditions. The internal web server is not enabled by default, which mitigates exposure. The CVSS v3.1 base score is 5.3, reflecting a network attack vector with no privileges or user interaction required, and impact limited to availability. No official fix or patch information is currently available.
Potential Impact
Successful exploitation results in denial of service due to uncontrolled memory allocation in the internal web server. There is no impact on confidentiality or integrity. Since the internal web server is disabled by default, the practical impact depends on whether the feature is enabled in the affected environment.
Mitigation Recommendations
As the internal web server is disabled by default, ensure it remains disabled unless necessary. Monitor official PowerDNS advisories for any forthcoming patches or mitigation instructions. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
