h2 is a pure-Python implementation of a HTTP/2 protocol stack. Versions up to and including 4.4.0 accept request header blocks containing more than one Host header, and forward every Host header to the consuming application. Where the consumer downgrades HTTP/2 to HTTP/1.1, the resulting request...

PYSEC-2026-1099 AIOHTTP's unicode processing of header values could cause parsing discrepancies

Summary The Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. Impact If a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker may be able to execute a request smuggling...

PYSEC-2026-1104 AIOHTTP is vulnerable to HTTP Request/Response Smuggling through incorrect parsing of chunked trailer sections

Summary The Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. Impact If a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker may be able to execu...

PYSEC-2026-1806 protobuf-python has a potential Denial of Service issue

Summary Any project that uses Protobuf pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit. Reporter: Alexis Challande, Trail of Bits...

PYSEC-2026-1103 aiohttp allows request smuggling due to incorrect parsing of chunk extensions

Summary The Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. Impact If a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker m...
