`HTTPPasswordMgr` can send saved HTTPS credentials via HTTP because of incorrect scheme matching
Vulnerability Description
The HTTPPasswordMgr class in the urllib.request module, along with its subclasses HTTPPasswordMgrWithDefaultRealm and HTTPPasswordMgrWithPriorAuth, did not take the URL scheme into account when matching stored credentials against a requested URL. Credentials added for an https:// URL were also used for requests to the same host over http://, so an attacker able to redirect or downgrade a client to plain HTTP (for example, via an HTTPS-to-HTTP redirect or an on-path position) could capture credentials in cleartext. Credentials added for http:// URLs could likewise be sent over https://.
Credential matching is now scoped by URL scheme. Credentials registered with a URL that includes a scheme are only used for requests with the same scheme. Credentials registered with a bare authority (such as example.com or example.com:8080) continue to match any scheme, preserving compatibility with existing code, including proxy authentication.
Users who cannot upgrade immediately can mitigate by ensuring that applications never make plain http:// requests to hosts for which credentials are registered, for example by not following redirects to http:// URLs.

Python 加密问题漏洞
Vulnerability Description
Python是Python基金会开源的一套开源的、面向对象的程序设计语言。该语言具有可扩展、支持模块和包、支持多种平台等特点。 Python 3.15.0之前版本存在安全漏洞,该漏洞源于urllib.request模块中的HTTPPasswordMgr类及其子类在将存储的凭据与请求的URL匹配时未考虑URL协议,可能导致攻击者通过重定向或将客户端降级为明文HTTP来捕获明文凭据。
