GHSA-7PPR-R889-MCF2 blaze: Unbounded WebSocket message aggregation in http4s-blaze-server

Summary http4s-blaze-server aggregates the fragments of an incoming WebSocket message with no limit on total size or fragment count. A client that completes a WebSocket handshake can send an unterminated fragmented message and drive unbounded heap growth in the server JVM, resulting in denial of...

GHSA-46Q4-43PH-C6FR blaze: Chunked-body trailer fields promoted into Request.headers in blaze-server (front-end header-sanitization bypass)

Summary blaze-server can merge HTTP/1.1 chunked-body trailer fields into Request.headers. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject arbitrary header names/values e.g. X-Forwarded-For, internal-auth headers that a fronting proxy sanitized from the...
