-------------------------------------------------------------------------

Package : python-urllib3 Version : 1.26.5-1~exp1+deb11u1 CVE ID : CVE-2023-43804 CVE-2023-45803 CVE-2024-37891 Debian Bug : 1053626 1054226 1074149 1089507

Multiple vulnerabilities were found in python-urllib3, an HTTP library with thread-safe connection pooling for Python, which could lead to information disclosure or authorization bypass.

CVE-2023-43804

It was discovered that the cookie request header wasn't stripped during cross-origin redirects. It is therefore possible for a user to specify a Cookie header and unknowingly leak information via HTTP redirects to a different origin if redirection isn't explicitly disabled.

CVE-2023-45803

It was discovered that the request body wasn't stripped when an HTTP redirect response using status 303 See Other, after the request had its method changed from one that could accept a request body (like POST) to GET as is required by HTTP RFCs.

CVE-2024-37891

It was discovered that the Proxy-Authorization request header isn't stripped during cross-origin redirects, when urllib3 is used without proxy support.

For Debian 11 bullseye, these problems have been fixed in version 1.26.5-1~exp1+deb11u1.

We recommend that you upgrade your python-urllib3 packages.
