Description
Impact
In ReactPHP's HTTP server component versions below v1.7.0, when ReactPHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host- and __Secure- confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-7070 and CVE-2020-8184 for more information.
Patches
Workarounds
Infrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any unexpected Cookie request headers.

NVD description
ReactPHP HTTP is a streaming HTTP client and server implementation for ReactPHP. In ReactPHP's HTTP server component versions starting with 0.7.0 and prior to 1.7.0, when ReactPHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like `__Host-` and `__Secure-` confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. This issue is fixed in ReactPHP HTTP version 1.7.0. As a workaround, Infrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any unexpected `Cookie` request headers.
