undici: undici: Denial of Service via unhandled error in WebSocket permessage-deflate decompression

A flaw was found in undici. A remote, unauthenticated attacker can trigger a Denial of Service DoS by sending a specially crafted compressed WebSocket payload. When this payload exceeds the 128 MiB decompressed-payload limit and contains a malformed DEFLATE byte, it causes an unhandled error in t...

SUSE CVE-2026-85024

undici bundles a WebSocket client whose permessage-deflate size-limit cleanup removes all listeners from the internal zlib inflate stream, including its error listener, while that stream can still emit. When a remote peer sends a compressed payload that crosses the built-in 128 MiB...
