The vulnerability describes a bypass of the maxAllocation parameter when using Brotli, Zstd, or Snappy compression, but this version predates both features: (1) the maxAllocation parameter was added in a later commit (fa97ee929d \"Make public API specify explicit maxAllocation to prevent OOM\"), and (2) Brotli/Zstd/Snappy HTTP decompression support was added in even later versions (first appearing in 4.1.109+). Version 4.1.21.Final only supports gzip/deflate decompression without any maxAllocation parameter.
