Google: dev-python/urllib3: security update to 18244.448.22

medium Tenable Cloud Security Plugin ID 451653

Description

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

 - urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't 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 is required by HTTP RFCs.
 Although this behavior is not specified in the section for redirects, it can be inferred by piecing
 together information from different sections and we have observed the behavior in other major HTTP client
 implementations like curl and web browsers. Because the vulnerability requires a previously trusted
 service to become compromised in order to have an impact on confidentiality we believe the exploitability
 of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request
 bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions
 must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information
 in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts
 redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised.
 This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve
 this issue. Users unable to update should disable redirects for services that aren't expecting to respond
 with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle
 301, 302, and 303 redirects manually by stripping the HTTP request body. (CVE-2023-45803)

Solution

Update the dev-python/urllib3 library and its related packages to version 18244.448.22 or later.
