CVE-2026-44432 urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion 1 during the second HTTPResponse.readamt=N call when the response was decompressed using the official Brotli library or 2 when...

CVE-2026-44432

CVE-2026-44432 affects urllib3 before 2.7.0, where the library could decompress the entire response during HTTPResponse.read or drain_conn, leading to high CPU and memory usage when handling highly compressed data. Affected versions: 2.6.0 up to (but not including) 2.7.0. Impact described as pote...

Decompression Bomb

Overview urllib3 is a HTTP library with thread-safe connection pooling, file post, and more. Affected versions of this package are vulnerable to Decompression Bomb either in HTTPResponse.read when Brotli is in use, or when HTTPResponse.drainconn is called after partial decompression has begun. An...

urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or...

GHSA-F6HV-JMP6-3VWV Netty: HttpContentDecompressor maxAllocation bypass when Content-Encoding set to br/zstd/snappy leads to decompression bomb DoS

Summary HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate encodings via ZlibDecoder, but is silently ignored when the content encoding is br Brotli, zstd, or...
