GitHub Vulnerability Alerts

CVE-2025-6176

Brotli versions up to 1.1.0 are vulnerable to a denial of service (DoS) attack due to decompression. This issue has been patched in Brotli version 1.2.0.

Additionally, this affects users who implement the Brotli decompression with Scrapy versions up to 2.13.2, leaving them vulnerable to a denial of service (DoS) attack. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occurs because brotli can achieve extremely high compression ratios for zero-filled data, leading to excessive memory consumption during decompression.

Release Notes

google/brotli (Brotli)

v1.2.0

Compare Source

SECURITY

• python: added Decompressor::can_accept_more_data method and optional
  output_buffer_limit argument Decompressor::process;
  that allows mitigation of unexpectedly large output;
  reported by Charles Chan (https://github.com/charleswhchan)

Added

• decoder / encoder: added static initialization to reduce binary size
• python: allow limiting decoder output (see SECURITY section)
• CLI: brcat alias; allow decoding concatenated brotli streams
• kt: pure Kotlin decoder
• cgo: support "raw" dictionaries
• build: Bazel modules

Removed

• java: dropped finalize() for native entities

Fixed

• java: in compress pass correct length to native encoder

Improved

• build: install man pages
• build: updated / fixed / refined Bazel buildfiles
• encoder: faster encoding
• cgo: link via pkg-config
• python: modernize extension / allow multi-phase module initialization

Changed

• decoder / encoder: static tables use "small" model (allows 2GiB+ binaries)
