python-httpx2: HTTPX2 is a next generation HTTP client for Python
CVE-2026-84382 is fixed in python-httpx2 on 1 platform by DEBIAN-CVE-2026-84382 (version 2.12.0-1), released September 8, 2026. It is not reported as exploited. Patch Radar priority: High.
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 iter_bytes() or aiter_bytes() yields bounded pieces to the application. A 64 KiB compressed chunk can expand to approximately 64 MiB in one intermediate allocation, so an attacker-controlled or compromised server can cause severe memory pressure or out-of-memory process termination even when the application streams the response. This issue is fixed in version 2.12.0.
