CVE-2026-84382

HTTPX2 is a next generation HTTP client for Python. Prior to 2.12.0, the HTTPX2 content decoders in src/httpx2/httpx2/decoders.py fully inflate each gzip, deflate, br, or zstd network chunk before iterbytes or aiterbytes yields bounded pieces to the application. A 64 KiB compressed chunk can expa...
