CVE-2026-84382 HTTPX2: Streaming response decompression does not bound peak memory (decompression amplification)

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...

CVE-2026-84382

HTTPX2 , a next-generation HTTP client for Python, contains a decompression amplification flaw in its content decoders (src/httpx2/httpx2/_decoders.py). Prior to 2.12.0 , the decoders fully inflate each gzip, deflate, br, or zstd network chunk before yielding bounded pieces via iter_bytes() or ai...

CVE-2026-84381

HTTPX2 is a next generation HTTP client for Python. Prior to 2.10.0, httpcore2 fails to start TLS in src/httpcore2/httpcore2/sync/socksproxy.py and src/httpcore2/httpcore2/async/socksproxy.py when the remote origin uses wss through a SOCKS5 proxy because the TLS upgrade condition only recognizes...

CVE-2026-84380

HTTPX2 , a next-generation HTTP client for Python, contains a request-smuggling vulnerability prior to version 2.11.0 . The flaw resides in Request._prepare() in _models.py, where its setdefault() logic checks Content-Length and Transfer-Encoding headers independently instead of treating them as ...

CVE-2026-84380 HTTPX2: Conflicting Content-Length and Transfer-Encoding headers can be auto-generated

HTTPX2 is a next generation HTTP client for Python. Prior to 2.11.0, Request.prepare in src/httpx2/httpx2/models.py can add a body-derived Content-Length header to a request that already contains a caller-supplied Transfer-Encoding header because its setdefault processing checks each default head...

CVE-2026-84379

HTTPX2 , a next-generation HTTP client for Python, is affected by a multipart part header injection vulnerability in FileField.render_headers() within src/httpx2/httpx2/_multipart.py. Prior to 2.11.0 , attacker-controlled content_type values and custom headers from files= tuples are interpolated ...

CVE-2026-84379 HTTPX2: Multipart part header injection via unvalidated file Content-Type and custom headers

HTTPX2 is a next generation HTTP client for Python. Prior to 2.11.0, FileField.renderheaders in src/httpx2/httpx2/multipart.py directly interpolates attacker-controlled contenttype values and custom headers from the files= three-element filename, content, contenttype tuple and the files=...

CVE-2026-84378 HTTPX2: Quadratic SSE line buffering can cause CPU denial of service

HTTPX2 is a next generation HTTP client for Python. From 2.5.0 until 2.10.0, the HTTPX2 Server-Sent Events parser in src/httpx2/httpx2/sse.py repeatedly copies and rescans buffered text in SSELineDecoder.decode when an attacker-controlled or compromised SSE endpoint splits one unterminated line...
