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 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-2026-47180 Zeroconf: Unbounded recursion in DNS compression-pointer decoder allows LAN-local denial of service

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

GHSA-XW9Q-2MV6-9FR8 Fedify has an incomplete SSRF mitigation after GHSA-p9cg-vqcc-grcx: validatePublicUrl allows special-use IPv4 ranges

Summary Fedify previously addressed SSRF/internal network access in GHSA-p9cg-vqcc-grcx by adding public URL validation before runtime document and media fetching. However, the current IPv4 validation logic appears incomplete. The validatePublicUrl protection relies on isValidPublicIPv4Address to...
