CVE-2026-85721: AsyncHttpClient's unbounded HTTP/1.1 response decompression enables a decompression-bomb denial of service

With automatic response decompression enabled (the default), the HTTP/1.1 path decompresses response bodies with no limit on the total output size. A hostile or compromised server, or an attacker who can change a response in transit, can send a small compressed body that inflates without bound in memory, exhausting the client’s heap and causing an OutOfMemoryError. gzip, deflate and snappy are always available as vectors; brotli and zstd apply only when those optional codecs are on the classpath.
