HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling via the parsing of Range headers. An attacker can potentially interfere with HTTP request processing by supplying non-ASCII decimals in the header, which may lead to unexpected parser mismatches. Remediation Upgra...

GHSA-MQQC-3GQH-H2X8 AIOHTTP has unicode match groups in regexes for ASCII protocol elements

Summary The parser allows non-ASCII decimals to be present in the Range header. Impact There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. ---- Patch:...

HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling via the unicode processing of HTTP header values. An attacker can bypass firewall or proxy protections by sending requests containing non-ASCII characters. Note: This is only exploitable if C extensions are not in...

GHSA-69F9-5GXW-WVC2 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...
