| CVE-2026-33261 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.9 MEDIUM |
| A zone transition from NSEC to NSEC3 might trigger an internal inconsistency and cause a denial of service. | |||||
| CVE-2026-33260 | 1 Powerdns | 3 Authoritative, Dnsdist, Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default. | |||||
| CVE-2026-33259 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.0 MEDIUM |
| Having many concurrent transfers of the same RPZ can lead to inconsistent RPZ data, use after free and/or a crash of the recursor. Normally concurrent transfers of the same RPZ zone can only occur with a malfunctioning RPZ provider. | |||||
| CVE-2026-33258 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| By publishing and querying a crafted zone an attacker can cause allocation of large entries in the negative and aggressive NSEC(3) caches. | |||||
| CVE-2026-33257 | 1 Powerdns | 3 Authoritative, Dnsdist, Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default. | |||||
| CVE-2026-33256 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default. | |||||
| CVE-2026-33254 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can create a large number of concurrent DoQ or DoH3 connections, causing unlimited memory allocation in DNSdist and leading to a denial of service. DOQ and DoH3 are disabled by default. | |||||
| CVE-2026-27854 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 4.8 MEDIUM |
| An attacker might be able to trigger a use-after-free by sending crafted DNS queries to a DNSdist using the DNSQuestion:getEDNSOptions method in custom Lua code. In some cases DNSQuestion:getEDNSOptions might refer to a version of the DNS packet that has been modified, thus triggering a use-after-free and potentially a crash resulting in denial of service. | |||||
| CVE-2026-27853 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 5.9 MEDIUM |
| An attacker might be able to trigger an out-of-bounds write by sending crafted DNS responses to a DNSdist using the DNSQuestion:changeName or DNSResponse:changeName methods in custom Lua code. In some cases the rewritten packet might become larger than the initial response and even exceed 65535 bytes, potentially leading to a crash resulting in denial of service. | |||||
| CVE-2026-24030 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly closed, but in some cases the system might enter an out-of-memory state instead and terminate the process. | |||||
| CVE-2026-24029 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 6.5 MEDIUM |
| When the early_acl_drop (earlyACLDrop in Lua) option is disabled (default is enabled) on a DNS over HTTPs frontend using the nghttp2 provider, the ACL check is skipped, allowing all clients to send DoH queries regardless of the configured ACL. | |||||
| CVE-2026-24028 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential information disclosure. | |||||
| CVE-2026-24027 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| Crafted zones can lead to increased incoming network traffic. | |||||
| CVE-2026-0398 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| Crafted zones can lead to increased resource usage and crafted CNAME chains can lead to cache poisoning in Recursor. | |||||
| CVE-2026-0397 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 3.1 LOW |
| When the internal webserver is enabled (default is disabled), an attacker might be able to trick an administrator logged to the dashboard into visiting a malicious website and extract information about the running configuration from the dashboard. The root cause of the issue is a misconfiguration of the Cross-Origin Resource Sharing (CORS) policy. | |||||
| CVE-2026-0396 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | N/A | 3.1 LOW |
| An attacker might be able to inject HTML content into the internal web dashboard by sending crafted DNS queries to a DNSdist instance where domain-based dynamic rules have been enabled via either DynBlockRulesGroup:setSuffixMatchRule or DynBlockRulesGroup:setSuffixMatchRuleFFI. | |||||
| CVE-2025-59030 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 7.5 HIGH |
| An attacker can trigger the removal of cached records by sending a NOTIFY query over TCP. | |||||
| CVE-2025-59029 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can trigger an assertion failure by requesting crafted DNS records, waiting for them to be inserted into the records cache, then send a query with qtype set to ANY. | |||||
| CVE-2025-59024 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 6.5 MEDIUM |
| Crafted delegations or IP fragments can poison cached delegations in Recursor. | |||||
| CVE-2025-59023 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 8.2 HIGH |
| Crafted delegations or IP fragments can poison cached delegations in Recursor. | |||||
