| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-33598 | 9.1 critical | 1.0% | powerdns, dnsdist | A cached crafted response can cause an out-of-bounds read if custom Lua code calls getDomainListByAddress() or getAddressListByDomain() on a packet cache. | Mon 26 Oct |
| CVE-2026-33602 | 8.2 high | 1.0% | powerdns, dnsdist | A rogue backend can send a crafted UDP response with a query ID off by one related to the maximum configured value, triggering an out-of-bounds write leading to a denial of service. | Mon 26 Oct |
| CVE-2026-33257 | 7.5 high | 1.0% | powerdns, authoritative, dnsdist, recursor | 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. | Mon 26 Oct |
| CVE-2026-33260 | 7.5 high | 1.0% | powerdns, authoritative, dnsdist, recursor | 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. | Mon 26 Oct |
| CVE-2026-33599 | 8.1 high | 0.00% | powerdns, dnsdist | A rogue backend can send a crafted SVCB response to a Discovery of Designated Resolvers request, when requested via either the autoUpgrade (Lua) option to newServer or auto_upgrade (YAML) settings. DDR upgrade is not enabled by default. | Mon 26 Oct |
| CVE-2026-33597 | 7.5 high | 0.00% | powerdns, dnsdist | PRSD detection denial of service | Mon 26 Oct |
| CVE-2026-33254 | 7.5 high | 0.00% | powerdns, dnsdist | 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. | Mon 26 Oct |
| CVE-2026-33593 | 7.5 high | 0.00% | powerdns, dnsdist | A client can trigger a divide by zero error leading to crash by sending a crafted DNSCrypt query. | Mon 26 Oct |
| CVE-2026-33594 | 7.5 high | 0.00% | powerdns, dnsdist | A client can trigger excessive memory allocation by generating a lot of queries that are routed to an overloaded DoH backend, causing queries to accumulate into a buffer that will not be released until the end of the connection. | Mon 26 Oct |
| CVE-2026-33595 | 7.5 high | 0.00% | powerdns, dnsdist | A client can trigger excessive memory allocation by generating a lot of errors responses over a single DoQ and DoH3 connection, as some resources were not properly released until the end of the connection. | Mon 26 Oct |
| CVE-2026-33596 | 6.5 medium | 0.00% | powerdns, dnsdist | A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend. | Mon 26 Oct |
| CVE-2026-42004 | 3.7 low | 0.00% | no CPE yet | An attacker can send a crafted EDNS OPT record that will be ignored by DNSdist’s filtering rules, but will be rewritten as a valid OPT record when EDNS Client Subnet is inserted, causing the backend to see the EDNS option(s) that DNSdist did not filter. | Sun 25 Oct |
