CoreDNS' DoQ worker pool does not bound stream backlog

Summary CoreDNS' DNS-over-QUIC DoQ server can be driven into large goroutine and memory growth by a remote client that opens many QUIC streams and stalls after sending only 1 byte. Even with a small configured quic workerpoolsize ... , CoreDNS still spawns a goroutine per accepted stream workers ...

CVE-2026-21720 Unauthenticated DoS: avatar cache leaks goroutines when /avatar/:hash requests time out

Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel...

CVE-2026-21720

CVE-2026-21720 affects Grafana’s /avatar/:hash handling: each uncached request spawns a goroutine to refresh Gravatar, and if the refresh sits in a 10-slot worker queue longer than three seconds the handler times out, causing the goroutine to block on an unbuffered channel. This can lead to linea...
