CVE-2026-48487

CVE-2026-48487 (python-zeroconf) : Prior to 0.149.16, _read_character_string and _read_string in zeroconf’s incoming protocol could advance the parser past the end of the payload by using attacker-declared RDLENGTH without checking against data length, enabling unauthenticated LAN-local hosts on ...

CVE-2026-48487

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.16, readcharacterstring and readstring in src/zeroconf/protocol/incoming.py advanced self.offset by attacker-declared RDLENGTH without checking it against self.datalen, allowing unauthenticated hosts on th...

CVE-2026-48045

The CVE-2026-48045 issue affects python-zeroconf (Zeroconf Pure Python) where AsyncListener.handle_query_or_defer retains every truncated TC-bit mDNS query per source in self._deferred[addr] and arms per-address timers in self._timers[addr]. This unbounded queue growth on LAN-local hosts (UDP/535...

CVE-2026-48045 Zeroconf: Unbounded TC-deferred queue allows LAN-local memory exhaustion via spoofed-source flood

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.12, AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query, each up to MAXMSGABSOLUTE = 8966 bytes, in self.deferredaddr and armed a per-address timer in self.timersaddr without...

CVE-2026-47184

CVE-2026-47184 affects the python-zeroconf project. DNSCache._async_add can insert every response record into cache, expirations, expire_heap, and service_cache without a cap, enabling unauthenticated LAN hosts on UDP/5353 (224.0.0.251 / ff02::fb) to multicast valid mDNS responses with unique nam...

CVE-2026-47184 Zeroconf: Unbounded DNS record cache allows LAN-local memory exhaustion via multicast flood

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.7, DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache without a cap, allowing unauthenticated hosts on the local link over UDP/5353 224.0.0.251 / ff02::f...

CVE-2026-47183 Zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.6, DNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dictionary keyed by attacker-influenced IncomingDecodeError messages, retaining sys.excinfo...

CVE-2026-47183

CVE-2026-47183 - zeroconf (python-zeroconf) : Affected versions prior to 0.149.6 store an unbounded in-memory log of exceptions in DNSIncoming._log_exception_debug and QuietLogger dedup, retaining frame locals with raw packet data. This enables any unauthenticated LAN host on UDP/5353 (224.0.0.25...
