Summary
Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
Security Fix(es):
* Scrapy: python-scrapy: brotli: Python brotli decompression bomb DoS (CVE-2025-6176)
