------------------------------------------------------------------------- Debian LTS Advisory DLA-3456-1 [email protected] https://www.debian.org/lts/security/ Markus Koschany June 18, 2023 https://wiki.debian.org/LTS

Package : requests Version : 2.21.0-1+deb10u1 CVE ID : CVE-2023-32681 Debian Bug : 1036693

Requests, a Python HTTP library, has been leaking Proxy-Authorization headers to destination servers when redirected to an HTTPS endpoint. For HTTP connections sent through the tunnel, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server.
However when sent over HTTPS, the `Proxy-Authorization` header must be sent in the CONNECT request as the proxy has no visibility into the tunneled request.
This results in Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious actor to potentially exfiltrate sensitive information.

For Debian 10 buster, this problem has been fixed in version 2.21.0-1+deb10u1.

We recommend that you upgrade your requests packages.

For the detailed security status of requests please refer to its security tracker page at:
