Vulnerability from osv_openeuler
Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces.
Security Fix(es):
When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, and parameters.(CVE-2026-0672)
The wsgiref.headers.Headers module has an HTTP header injection vulnerability where user-controlled header names and values containing newlines can allow injecting malicious HTTP headers.(CVE-2026-0865)
