Summary Mail::Utilities.qvaluedecode and Mail::Utilities.bvaluedecode decoded only the first RFC 2047 encoded-word in a string and used an overly greedy pattern to match the charset token. A crafted, malformed encoded-word embedded in an address display name or local part could cause the decoded...

CVE-2026-63385

A flaw was found in libevent. The evhttpdecodeuriinternal function in http.c decodes percent-encoded %00 bytes into literal NUL characters without rejecting them, allowing an attacker to craft a URI such as /admin/secret%00.jpg where extension-based access checks see .jpg but the server processes...

CVE-2026-59822

A flaw was found in LiteLLM, a proxy server designed for Large Language Model LLM APIs. An unauthenticated attacker could exploit a vulnerability in the MCP Streamable HTTP endpoint. By using a fabricated Authorization header, the attacker could bypass the standard key validation, gaining...

CVE-2026-84380

A flaw was found in HTTPX2, a Python HTTP client. The Request.prepare function can incorrectly add a Content-Length header to a request that already includes a Transfer-Encoding header. This conflict in HTTP framing headers can lead to request smuggling or connection desynchronization. This could...

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-2026-84379

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-2026-84380

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-2026-84380

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...
