Linux Distros Unpatched Vulnerability : CVE-2026-84382

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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,...

CVE-2026-84379

A flaw was found in HTTPX2, a Python HTTP client. A remote attacker could exploit this vulnerability by sending specially crafted multipart/form-data requests. The FileField.renderheaders function fails to validate Content-Type values and custom headers, allowing the injection of Carriage Return ...

CVE-2026-84382

A flaw was found in httpx2, a Python HTTP client. The content decoders in httpx2 fully inflate compressed network chunks such as gzip, deflate, br, or zstd before yielding bounded pieces to the application. This can lead to a small compressed chunk expanding significantly in memory, for example, ...

CVE-2026-84380

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 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-2026-84382 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: 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-2026-84378

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...

PT-2026-84846

Name of the Vulnerable Software and Affected Versions HTTPX2 versions prior to 2.11.0 Description The Request. prepare function 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. This occurs...

urllib3: urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via ProxyManager.connectionfromurl.urlopen with assertsamehost=False, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitiv...
