Insufficiently Protected Credentials

Overview @hapi/wreck is a HTTP Client Utilities library. Affected versions of this package are vulnerable to Insufficiently Protected Credentials due to leaking the sensitive Proxy-Authorization header across cross-hostname redirects. An attacker can obtain sensitive proxy credentials by inducing...

@hapi/wreck leaks sensitive `Proxy-Authorization` header across cross-hostname redirects

Impact When @hapi/wreck follows a 3xx redirect to a different hostname, only the Authorization and Cookie headers are stripped. The standard credential header Proxy-Authorization is forwarded intact to the redirect target, potentially exposing forward-proxy credentials to a host outside the...

Astra Linux – Vulnerability in requests

Requests is an HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to destination servers when redirected to an HTTPS endpoint. This issue arises due to the way we use rebuildproxies to reattach the Proxy-Authorization header to requests. For HTTP connections...

Astra Linux – Vulnerability in python-urllib3

urllib3 is a user-friendly HTTP client library for Python. When using urllib3’s proxy support with ProxyManager, the Proxy-Authorization header is only sent to the configured proxy, as expected. However, when sending HTTP requests without using urllib3’s proxy support, it’s possible to accidental...
