VCID-1mgq-74b9-4bcg 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. CVE-2026-33595
VCID-744k-b7s7-kbh5 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. CVE-2026-33599
VCID-7xds-447f-qufr 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. CVE-2026-33596
VCID-a65j-y7z3-fudk 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. CVE-2026-33602
VCID-afun-gxhy-rbed A client can trigger a divide by zero error leading to crash by sending a crafted DNSCrypt query. CVE-2026-33593
VCID-chzq-qej6-rkdq 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-2026-33257
VCID-fbsf-bbw7-kyah PRSD detection denial of service CVE-2026-33597
VCID-nrex-hpxg-ekhs 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. CVE-2026-33594
VCID-pfhu-1qdf-p7d5 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-2026-33260
VCID-qc7c-1d8j-hfha A cached crafted response can cause an out-of-bounds read if custom Lua code calls getDomainListByAddress() or getAddressListByDomain() on a packet cache. CVE-2026-33598
VCID-ytdy-s1ug-dkh7 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-2026-33254
