2.31.0 (2023-05-22)

Security - Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential

forwarding of Proxy-Authorization headers to destination servers when following HTTPS redirects.

When proxies are defined with user info (https://user:pass@proxy:8080), Requests will construct a Proxy-Authorization header that is attached to the request to authenticate with the proxy.

In cases where Requests receives a redirect response, it previously reattached the Proxy-Authorization header incorrectly, resulting in the value being sent through the tunneled connection to the destination server. Users who rely on defining their proxy credentials in the URL are strongly encouraged to upgrade to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy credentials once the change has been fully deployed.

Users who do not use a proxy or do not supply their proxy credentials through the user information portion of their proxy URL are not subject to this vulnerability.

Full details can be read in our ​Github Security Advisory and ​CVE-2023-32681.

According to ​https://vuldb.com/?id.229726, the temporary CVSS score is 3.6. /me thinks it seems very low.
