Package : python-urllib3
Version : 1.24.1-1+deb10u2
CVE ID : CVE-2023-43803
Debian Bug : 1054226

It was discovered that python-urllib3, a user-friendly HTTP client
library for Python, did not remove the HTTP request body when an HTTP
redirect response using status 301, 302, or 303 after the request had
its method changed from one that could accept a request body, like POST,
to GET, as required by the HTTP RFCs. This could lead to information
disclosure.

For Debian 10 buster, these problems have been fixed in version
1.24.1-1+deb10u2.

We recommend that you upgrade your python-urllib3 packages.
