Echo: python-urllib3: security update to 2.3.0-3+e3urllib3: security update to 2.6.3+echo.1

high Tenable Self-Hosted Container Security Plugin ID 463788

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the
 whole response instead of the requested portion (1) during the second HTTPResponse.read(amt=N) call when
 the response was decompressed using the official Brotli library or (2) when HTTPResponse.drain_conn() was
 called after the response had been read and decompressed partially (compression algorithm did not matter
 here). These issues could cause urllib3 to fully decode a small amount of highly compressed data in a
 single operation. This could result in excessive resource consumption (high CPU usage and massive memory
 allocation for the decompressed data) on the client side. This vulnerability is fixed in 2.7.0.
 (CVE-2026-44432)

Solution

Update the python-urllib3 library and its related packages to version 2.3.0-3+e3 or later.
